Anyhow, I've made a weird discovery that I found interesting. After the other info you gave me, I am less concerned with the kernel now. I would still upgrade it, though. There is a nasty networking bug in the 2,4,9 kernel, I believe, that effects scalability. It seems like there's a barrier when the JVM consume around 90MB of RAM. Once the JVM got over that barrier, then things will keep working. You may be dealing with garbage collection issues. If the GC gets going before that, it will lock everything up while it GCs. Try messing with the following options: -Xms and -Xmx using CATALINA_OPTS set in the startup script. For example: CATALINA_OPTS=-Xms128M -Xmx2048M would set the heap size minimum to 128meg and would force garbage collection at 2048meg. Play with that and see how it affects the slowdown. You can alos set two other options to help out debugging: -Xincgc and -Xloggc:gcinfo.log I forgot what the first setting does (ingrease GC?) but the second one turns on logging when it garbage collects. If you watch that file as the failure happens, you can tell if garbage collecting is having an effect or not.

Re: MOD_JK.SO
I got this on Apache 1.3.27. I assume you downloaded the binary mod_jk.so. Make sure that you got that fits your use or non-use of SSL in the server. Not sure where you got the binary, but there is a note on the jakarta connector download page that lists which binary is for which. I myself just compiled the connector from source; I could not get the binary connector to work with Apache without getting that error.

Re: Will Upgrade from one cpu to Dual CPU benefit tomcat 3.2.4 ?
I find that with databases in general, and MySQl in particular, that you CPU is bound up in a io wait state, that is, waiting for disk reads and/or writes. You may be disk bound. In that case, adding another CPU will only give you nominal improvement. You would need to check to see if I/O is the issue by checking the I/O wait states and see if the kernel is just blocking the CPU waiting for disk read/writes. If so, are you using SCSI? IDE? Got RAID? Striping will improve the situation, as well as turning off mirroring disks, if you have that setup.

mod_jk error and Header dumping
I am running using Apache 1.2.6 talking to two Tomcat 4.0.5 (I think that is the version number; how do you verify it? The Tomcat default page comes up with just '4.0') listening on two separate ports. I am seeing a strange problem. We have a customized web application which we run through Tomcat. In one particular module, we have an issue: on several pages sent from Apache, there is HTTP protocol header information displayed at the top of the page. Here is some text from it: HTTP/1.1 200 OK Date: Yue, 19 Nov 2002 22:31:05 GMT Server: Apache/1.3.26 (Unix) mod_jk/1.2 Keep-Alive:...

jk1.2 load-balancing help needed
I am running a web application that has 2 Apache instances listening on 4 total interfaces (to account for NIC failure) using mod_jk to load-balance across 4 tomcat instances.I have two boxes with two tomcats on each box listening on seprate interfaces (again, for Nic failure). Apache is version 1.3.27 with mod_jk 1.2. Tomcat is version 4.0.6. Picture it like this: Apache 1Apache 2 -- -- + Apache + + Apache + + mod_jk + + mod_jk + -- -- Java Server 1 Java Server 2 -- -- + Tomcat 1 + + Tomcat 3 + + Tomcat 2 + + Tomcat 4 + -- -- We ran into a production issue due to a hung query that was run a number of times. It caused a number of users to get hung requests. They were able to fix the problem by restarting their browser. What normally happens is that our load is such that Tomcat1 gets almost all the requests. When Tomcat1 gets too busy (all the ajp13 processors are full and a new session is requested, the request gets routed to Tomcat2, and so on for Tomcat 2, 3, and 4. Because our load is low right now, we never get requests to Tomcats 3 and 4. However, once a hung query started eating up database (and therfore, AJP13 connections which were waiting for the DB to return) the new connections got routed to the other Tomcats. Tomcat failed over, basically. This leads me to my request: I would like to do true round-robin load-balancing on all four tomcats to minimize the impact of problems like we just saw. Since all connections are normally handled by Tomcats 1 and 2, a problem that occurs in Tomcats 1 and 2 has an effect on amost all the users. However, if the users were round-robin load-balanced and Tomcat 1 hit the bad query enough to hose all its connections it had, only those in Tomcat1 would be affected; the ones in Tomcats 2,3, and 4 would be unaffected. How can one change the weights to get new request, round-robin load-balancing from mod_jk? Does this make sense to anyone? I checked the connectors documentation, but nothing explains why Tomcat1 gets all the new connections. It appears to me that round-robin is not working? Here is my workers.properties file. it is identical on both Apache servers: --Begin workers.properties # # workers.properties # # In Unix, we use forward slashes: ps=/ # list the workers by name worker.list=tomcat1,tomcat2,tomcat3,tomcat4,loadbalancer # # First tomcat server # worker.tomcat1.port=11009 worker.tomcat1.host=10.1.2.45 worker.tomcat1.type=ajp13 # Specify the size of the open connection cache. #worker.tomcat1.cachesize # # Specifies the load balance factor when used with # a load balancing worker. # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat1.lbfactor=100 # # Second tomcat server # worker.tomcat2.port=12009 worker.tomcat2.host=10.1.2.145 worker.tomcat2.type=ajp13 # Specify the size of the open connection cache. #worker.tomcat2.cachesize # # Specifies the load balance factor when used with # a load balancing worker.# Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat2.lbfactor=100 # # Third tomcat server # worker.tomcat3.port=11009 worker.tomcat3.host=10.1.2.12 worker.tomcat3.type=ajp13 # Specify the size of the open connection cache. #worker.tomcat2.cachesize # # Specifies the load balance factor when used with # a load balancing worker. # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat2.lbfactor=100 # # Fourth tomcat server # worker.tomcat4.port=12009 worker.tomcat4.host=10.1.2.112 worker.tomcat4.type=ajp13 # Specify the size of the open connection cache. #worker.tomcat2.cachesize # # Specifies the load balance factor when used with # a load balancing worker. # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat2.lbfactor=100 # # Load Balancer worker # # # The loadbalancer (type lb) worker performs weighted round-robin # load balancing with sticky sessions. # Note: # If a worker dies, the load balancer will check its state #once in a while.

Problem with Tomcat 4
I have a installation of Apache/Tomcat which is working...sort of. I have everything configured according to the snippets I will post below. Here is the strangeness: I initially configured Tomcat as standalone and was able to pull up the servlet app perfectly well. Everything performed as expected. Now when I call the URL mapped to Tomcat, I get a blank, well-formed HTML page! That is 'HTMLBODY/BODY/HTML'. My pertinent configs are below. I setup the workers.properties as loadbalanced because I could only find a complete config in this form. --First, My httpd.conf stuff-- # Mod_jk configuration LoadModulejk_module libexec/mod_jk.so AddModule mod_jk.c JkWorkersFile /usr/local/apache/conf/workers.properties JkLogFile /usr/local/apache/logs/mod_jk.log JkLogLevelinfo JkLogStampFormat [%a %b %d %H:%M:%S %Y] JkMount /servlets/* loadbalancer JkMount /*.jsp loadbalancer --Next,my workers.properties-- # Using Single Tomcat Instance using AJPV13 # #workers.tomcat_home=/usr/local/tomcat #workers.java_home=/usr/local/jdk ps=/ worker.list=tomcat1, loadbalancer # Definition for Ajp13 worker (Ajp12 left to readers imagination) # worker.tomcat1.port=8009 worker.tomcat1.host=remotehost.wellinx.com worker.tomcat1.type=ajp13 # Specifies the load balance factor when used with a load balanced # worker # # Note: # - lbfactor must be 0 # - The lower the lbfactor the less work done by worker worker.tomcat1.lbfactor=100 # # Load Balancer worker # # # The loadbalancer (type lb) worker performs weighted round-robin # load balancing with sticky sessions. # Note: # If a worker dies, the load balancer will check its state #once in a while.

Re: Installation on Linux
You need mod_jk or mod_webapp in order to hava Apache forward servlet requests to Tomcat. The major difference between mod_jk and mod_webapp is that mod_jk allows for load balancing over multiple Tomcat instances while mod_webapp does not. I hava also heard that mod_webapp should have that capability (soon?) but does not have it now. I have heard of people using Apache 2.x with Tomcat, but I have not done that myself.

Just for clarification, doing tomcat.pid wouldn't really work, because
all you would get is the ps entry for that value. You'd have to use cut

resulted
from ps -ef | grep java | grep myapp and redirect it to tomcat.pid.

A relatively unix-flavor-independent way to do it is to give your process

You would then do ps -ef | grep java | grep myapp tomcat.pid.

Re: tomcat.log
You want to turn down the logging level in the server.xml file; if it is info, change it to 'warn'. Also, you could use logrotate running at a certain time frame to watch the log for a specific size and then roll it. I am not sure what issues this raises with Tomcat alone. With apache, you have to HUP it (on Unix).

Re: Developing on a different platform from production
It depends on what you mean by 'test'. If you are doing load testing, then obviously this will not do as the platform and OS can dictate performance. Also, there are differing problems in the jdks based on platform: Sun jdk w/Hotspot has had some problems lately which do not crop up on the other jdks (Sun's jdk is usually ahead of Linux's, or so I have noticed. 1.3 was in beta well after 1.3 was released for Sun). However, if you are just talking about functional testing, I think going to a Linux box is Ok. Btw, have you seen the new Netra series of Sun boxes? They are damn cheap and may be an alternative to Linux. I myself suport a web app that runs on Linux is production but will move to a Linux/Sun load balanced solution soon.

RE: Running multiple tomcat instances ?????
If that script works, then great.
A less elegant way to do it would be to utilize pgrep. Do a man on it
(not sure what platform you are running on). You can pgrep for the
earliest PID that was run with a number of options. I use it for a Jserv
installation and it works quite nice.
I have not tested it with Tomcat, though.

Problem with JK 1.2.0 docs?
I am confused by the build process for mod_jk 1.2.0 on a Redhat 7.3 server. From the 'BUILDING' text file, it says: use configure and indicate Apache 1.3 apxs location (--with-apxs) use make copy the mod_jk binary to the apache modules location Now, after doing a 'make' there is no binary in the top-level directory with the configure script (i.e., jakarta-tomcat-connectors-jk-1.2.0-src/jk/native). So I went into jakarta-tomcat-connectors-jk-1.2.0-src/jk/native/apache-1.3 and I see the following files: [root@javatest2 apache-1.3]# ls -l total 1556 -rw-r--r--1 root root 120 Sep 26 04:34 libjk.module -rw-r--r--1 root root 2350 Oct 9 11:27 Makefile -rw-r--r--1 root root 659 Oct 9 11:27 Makefile.apxs -rwxr-xr-x1 root root 582 Sep 26 04:34 Makefile.apxs.in -rwxr-xr-x1 root root 2234 Sep 26 04:34 Makefile.in -rw-r--r--1 root root 252 Sep 26 04:34 Makefile.libdir -rw-r--r--1 root root 827 Sep 26 04:34 Makefile.tmpl -rw-r--r--1 root root 920456 Oct 9 11:28 mod_jk.a -rw-r--r--1 root root66958 Sep 26 04:34 mod_jk.c -rw-r--r--1 root root 7326 Sep 26 04:34 mod_jk.dsp -rw-r--r--1 root root 11 Sep 26 04:34 mod_jk.exp -rw-r--r--1 root root 713 Oct 9 11:28 mod_jk.la -rw-r--r--1 root root 103752 Oct 9 11:28 mod_jk.lo -rw-r--r--1 root root 101844 Oct 9 11:28 mod_jk.o lrwxrwxrwx1 root root 15 Oct 9 11:28 mod_jk.so - mod_jk.so.0.0.0 lrwxrwxrwx1 root root 15 Oct 9 11:28 mod_jk.so.0 - mod_jk.so.0.0.0 -rwxr-xr-x1 root root 326225 Oct 9 11:28 mod_jk.so.0.0.0 So which is the binary?

I was thinking about doing a similar thing...using the http connector (which

server to communicate with the tomcat manager app
(http://tomcat1:8080/manager/reload?path=/mywebapp). I would think it would
be easy enough to write a script that uses Lynx to invoke this same URL on
all four servers. I don't think it is a problem to be restarting tomcat
frequently, at least I have not seen a problem and we've done this quite a
bit in our QA environment.
Ben, may I see the script that you are currently using to restart tomcat on
the multiple servers? Also, have you done any load testing? If so, what
sort of load is your system able to support?

Re: Using daemontools to supervise Tomcat
I tried to get Daemontools running for Jserv (which is pretty similar) and had no luck. My guess is that you might be able to get it to work if you pass all the env variables using daemontools and just launch java. However, since java is not a normal daemon, you will probably need fghack to do it. I myself gave up; the thought of creating all those environment variables was just too much, so I just rolled my own PID monitor whcih I am porting to Tomcat. Basically, it will grep out the PID and write to a file which I watch with a cronjob process.

I use a -Dafoo to give the process a unique identifier. This sets a marker on the process but does nothing for the JVM itself. To find a process ID, I would use 'pgrep -f foo' and the PID is returned (this is on Unix, btw). Also , when you do the '-Dafoo' as the first arg to the JVM, it appears in 'ps -ef'. Here is how I do it: I setup the java command line like so: /usr/local/jdk/bin/java \ -Da=Ftp \ -cp $PROP_DIR:$EXT_INT_JAR:$NET_COMPONENTS_JAR:$LOG4J_JAR \ com.usrx.extinterface.ftp.FTPService $PROPERTIES_FILES \ $LOG_FILE 21 Then I do this: pgrep -fn Ftp $PIDFILE Technically, you do not need the 'n', as that denotes the newest process. You can get by with just the -f. Finally, I run the following script through cron every minute. The variables should be self-explanatory. For security reasons, I cannot divulge the whole setup.

Re: Connecting Apache with remote Tomcat
I run mod_jk 1.2.0 and I do not need to recycle Apache when restarting Tomcat. I did notice a lag of up to 2 minutes after restarting Tomcat where Apache will not take requests. I think this is due to Tomcat restarting itself and classloading. Maybe you do not wait long enough after restarting Tomcat before you retry a connection? FYI, I am running two Apache 1.3.27 on Redhat load balancing across 4 Tomcats on two Solaris 8 servers.

I've had real trouble getting this to work with either startup.sh or catalina.sh but I'm putting this down to the fact that I'm no genius with unix processes... I don't really understand what the issue is here, but I plead ignorance in that I haven't worked with the DJB tools in a while. But, as I recall, the tools simply execute the program using the (by default) 'run' script. When run exits, for whatever reason, the tools fire it back up. Now the tomcat startup scripts fire the java process off in the background, but as I recall there is an option to NOT do that, and simply have tomcat.sh stay in the foreground. It seems to me that a few simple tweaks to tomcat.sh, linked to 'run' in the proper spot, and it should Just Work. Lemme look. This man has a bad heart. Angina Pectoris, but we have the cure...Yes. Here they are... Yes, here it is, just start catalina.sh with the run option, and it doesn't fork into the background. #!/bin/sh # daemontools run script for Tomcat cd /usr/local/java/jakarta-tomcat-4.0.4/bin # start tomcat in the foreground, redirect stderr to stdout for logging. exec ./catalina.sh run 21 Copy or link this script to /services/tomcat/run, and it should fire right up. Untested, but it should work. Multilog should work with this as well, as the 'run' option doesn't redirect stdout or stderr, whereas the (default) 'start' option does. Since multilog only listens to stdin, the script redirects stderr to stdout so it can be captured as well. You need to setup the log directory properly, as mentioned in DJBs faq. The key is to keep the java process in the foreground for the 'run' script. supervise puts it in the background for you, so that's why the run script doesn't need to.

Btw, I am running an App that has roughly 20k hits per day using a 99% dynamically generated web app (this is a rather small web app compared to others out there on the list) and I rely on it in a life or death situation (i.e., I get fired if I cannot keep up a 99% uptime requirement for 24/7/365).

Re: Two instances of Tomcat
Remember that with 2 Tomcats, you need DOUBLE the memory. You may be attempting to use more memory then you have in the box. Use 'top' to watch the memory utilization and see if you are filling up on memory to create the spreadsheet thingy. You can control the memory usage of Tomcat using the -Xmx and -Xms to control heap size. The settings you list would mean that you would need, at least, 1.1gig of memory in the box to utilize both Tomcats to their potential.

RE: Apache-Tomcat mod_jk
You seem to be confused here. I believe you said you were accessing port
8080 when it was working. Now, unless you setup Apache to listen on port
8080, you were talking directly to Tomcat's web server. Now that you
have moved to Apache, you want to drop the 8080 and use port 80, which
Apache listens to by default (again, unless you changed it).
I would suggest that you post all the lines you added to httpd.conf,
your workers.properties conf file, and your server.xml file.
The JkMount directive tells Apache what path gets mapped to Tomcat; see
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/mod_jk-howto.html for
more information about the directive.

You don't need ant. When I originally wrote the HOWTO, I thought you
did, so I hacked through getting it to work and put that in my
HOWTO. Then,
based on a tip from someone on the list I learned that I
didn't need to go
through all that, all I needed to do was follow connector
build option #2,
which is using the standard ./configure method.
So, basically, if you want to build the connector from source, all you
have to do is (assuming a GNU-ready build environment):
NOTE: the ./configure method assumes you have a sane build
environment:
libtool, GNU make, autoconf, m4
a) cd to CONNECTOR_HOME/jk/native.
b) check README and README.configure.
c) run buildconf.sh: ./buildconf.sh. This will create a file called
configure in CONNECTOR_HOME/jk/native.
d) run configure: ./configure
--with-apxs=/some/path/to/apache/bin/apxs
--with-java-home=${JAVA_HOME}
e) run make: make
g) You should end up with a mod_jk.so file in
CONNECTOR_HOME/jk/native/apache-1.3. Copy that mod_jk.so file to
/path/to/apache/libexec/.

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html.
Another good How-to that I used to setup a load-balanced
Apache-mod_jk-Tomcat 4.0.6 setup is at http://www.ubeans.com/tomcat/.
Good luck,

You seem to be confused here. I believe you said you were accessing port
8080 when it was working. Now, unless you setup Apache to listen on port
8080, you were talking directly to Tomcat's web server. Now that you
have moved to Apache, you want to drop the 8080 and use port 80, which
Apache listens to by default (again, unless you changed it).
I would suggest that you post all the lines you added to httpd.conf,
your workers.properties conf file, and your server.xml file.
The JkMount directive tells Apache what path gets mapped to Tomcat; see
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/mod_jk-howto.html for
more information about the directive.

Thank you very much for your help. The instructions were easy enough
to follow, with a few exceptions. I downloaded the
mod_jk-1.3-eapi.so because
as per the site, that was the module to use if I am running
Apache 1.3 with
mod_ssl. After doing all the steps I tried to restart Apache
and got the
following error message:
Starting httpd: Syntax error on line 4 of

Cannot load /etc/httpd/libexec/mod_jk.so into server:
/etc/httpd/libexec/mod_jk.so: cannot open shared object file: No such
file or directory
I changed the path in the mod_jk.conf file to LoadModule jk_module
/the/exact/path/to/mod_jk-1.3-eapi.so
When I tried to restart Apache it restarted no problem. But now I
cannot get to http://localhost:8080 when before I could.
(http://localhost still
works though) Any thoughts? In the meantime I am going back
to double
check everything.

#1: Yes.
#2: No. :)
You don't need ant. When I originally wrote the HOWTO, I thought you
did, so I hacked through getting it to work and put that in my
HOWTO. Then,
based on a tip from someone on the list I learned that I
didn't need to go
through all that, all I needed to do was follow connector
build option #2,
which is using the standard ./configure method.
So, basically, if you want to build the connector from source, all you
have to do is (assuming a GNU-ready build environment):
NOTE: the ./configure method assumes you have a sane build
environment:
libtool, GNU make, autoconf, m4
a) cd to CONNECTOR_HOME/jk/native.
b) check README and README.configure.
c) run buildconf.sh: ./buildconf.sh. This will create a file called
configure in CONNECTOR_HOME/jk/native.
d) run configure: ./configure
--with-apxs=/some/path/to/apache/bin/apxs
--with-java-home=${JAVA_HOME}
e) run make: make
g) You should end up with a mod_jk.so file in
CONNECTOR_HOME/jk/native/apache-1.3. Copy that mod_jk.so file to
/path/to/apache/libexec/.

I ended up using mod_webapp.so, which is another connector. It's located in the jakarta-tomcat-connectors-4.1.12-src.tar.gz, which you can download from http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.12/src/ (the same directory as tomcat itself).

This would be done by Apache (though it could possibly be done by Tomcat; I use Apache). You can do it one of two ways: 1) Use mod_rewrite to rewrite /index.html to /path-to-context-name. Not sure on the mechanics of this. Try the Apache list for pointers, or any number of tutotials on mod_rewrite. 2) Use the 'Redirect' directive in Apache.

JAVA_HOME problem with 4.1.18
I have this weird problem with setting the JAVA_HOME env variable in Tomcat 4.1.18 (I also had it in 4.1.17). Here is the lines from my startup.sh: CATALINA_HOME=/usr/local/tomcat1-new JAVA_HOME=/usr/local/j2re1.4.1_01 JAVA_OPTS=-ms32m -mx200m export CATALINA_HOME JAVA_HOME JAVA_OPTS This setup worked in 4.1.12 and 4.0.6. Now, when I start Tomcat using the startup.sh, I get this: [root@dev bin]# ./startup.sh The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program What gives?

Mod_jk/Tomcat issue?
We saw a strange production issue this morning that seems to be related to Apache/mod_jk but I wanted to see if anyone can shed some lght on it. First, the environment: 2 Redhat 7.3 Linux server talking to 2 Sun Solaris 8 Tomcat 4.0.6 servers. Each server has 2 separate Tomcat instances for a total of 4. The Java uses Oracles JDBC drivers (not through Tomcat, but through a custom connection pool) to talk to an Oracle DB runnin on AIX 4.x. The first symptom was a huge spike in DB usage due to the creation of around 35 pooled connections to the database, This led us to think something happened on the database side, but it seems that the pool only grew on one of the Tomcat instances; the other instances showed the default pool size. The Oracle database did not show any locked tables or huge, hanging queries. The only problems I see in logs are related to mod_jk and Tomcat. First in the Tomcat engine log,I see: 2002-12-23 09:07:14 Ajp13Connector[12009] No processor available, rejecting this connection There are hundreds of these messages. Then I start seeing this message in the engine log: 2002-12-23 09:07:28 Ajp13Processor[12009][18] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) About a minute after, in the mod_jk logs, I see: [Mon Dec 23 09:08:29 2002] [jk_ajp_common.c (679)]: ajp_connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [Mon Dec 23 09:08:29 2002] [jk_ajp_common.c (1041)]: Error reading reply [Mon Dec 23 09:08:29 2002] [jk_ajp_common.c (1178)]: In jk_endpoint_t::service, ajp_get_reply failed in send loop 0 This goes on for about 20 seconds before I see a huge number of the following: [Mon Dec 23 09:08:49 2002] [jk_ajp_common.c (961)]: Error ajp_process_callback - write failed I am at a loss at what might cause this.

Urgent - Issue with Tomcat/mod_jk?
I posted a message earlier which has not received any replies so I will try another tact. The earlier mail is posted below this one. I have a production issue that has arisen in a setup of two Apache 1.3.27/Redhat 7.3 servers load-balanced across 4 Tomcat 4.0.6/Sun Solaris servers. Tomcat is running with Sun's 1.3 JVM. We have gotten a lot of the following errors in the engine log for Tomcat: 2002-12-23 15:21:56 Ajp13Processor[12009][16] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) We have also gotten calls from customers saying they are getting hanging screens in our application. We see no anomolies on out database, although earlier we did. Can anyone tell me what the error above is saying? Is it not able to write to the mod_jk? It looks like it is failing in some sort of closing routine (org.apache.ajp.tomcat4.Ajp13Response.finishResponse). Could this be a protocol issue? I am getting heat from my bosses on this one and I need to say SOMETHING! Please help if you can give me any clues or suggest possibilities.

Re: Urgent - Issue with Tomcat/mod_jk?
I had suspected that in the problem earlier in the day (the part of the email I posted at the end if the last email you replied to). However, what did not make sense was the connection pool woth the database also going up. If I understand the stuff below, after 85 concurrent connections (max connections + accept count) I would start getting the Out of Processors error. However, I cannot see how this would cause the DATABASE connection pool to grow as large as it did (we usually handle 50k connections a business day with 5 pooled connections; during the earlier problem, the database connections went to *30*, our maximum). Additionally, why would we contine to get the following error: 2002-12-23 09:07:28 Ajp13Processor[12009][18] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) without seeing the Out of Processor msgs?

RE: Urgent - Issue with Tomcat/mod_jk?
I beleive we are dealing with a different problem. My app has been running on Tomcat 4.0.6 for weeks until I had the problem recently. There was no crash. What happened was, it seems, a user REALLY fat-fingered the enter key or some smart person sent the same request to the server 180 times within one minute. I traced back through my access logs for Apache and caught the massive number if requests for one URL at the same time I had the problem. All of these requests overwhelmed the number of AJP13 processors I had configured (well, they are still at the default setting) and also caused a massive opening of database connections. Anyway, as to your problem: You may not have enough memory setup for your JVM. Do you send amx -Xm and -Xs parameters to Tomcat using JAVA_OPTS? You may be getting more load then Tomcat can handle due to a RAM constraint.

RE: running tomcat as a non-root user?
Additionally, you can add the su tomcat -c in a wrapper script that calls the startup.sh file. Mine looks like this: case $1 in start) echo -n Starting Tomcat... /bin/su tomcat -c /usr/local/tomcat1/bin/startup.sh /bin/su tomcat -c /usr/local/tomcat2/bin/startup.sh ;; That way, you CAN use root (and a startup script) to start Tomcat and still get the security benefits of running as an unpriveledged, locked user.

RE: is this normal??
There is probably a problem going on there. I find it strange that you have so much cumulative CPU time on the httpd processes. To me, they look hung (in so far as I can tell). Since most apps are transactional in nature (i.e., individual requests being fulfilled rather quickly), you would expect to see the Apache processes using CPU, then giving it up rather quickly. Of course, other httpd processes will also pop in and out of CPU usage as individual requests pop in. How long has this Apache/Tomcat been running? You might try a restart of both and see if the same behavior comes right back or if it takes time. You may have an issue in the app which is triggering a hang. Of course, on a pretty busy web server, you may get such cumulative times, but you should still see httpd processes popping in and out of CPU usage as they handle their respective requests. If the same PIDs sit there pegging the CPU incessently, you most likely have an issue.

RE: is this normal??
I found a trick that might help: up your sar reports to take a snapshot every minute. Then, when you notice the CPU pegging, go through the sar reports for CPU usage and try to find the minute that they start. Then, you can go back through the Apache access logs (mod_jk.log perhaps), etc. to see if you can correlate a specific request with the the problem.

Are you using Linux? Linux shows in-process threads as processes. If you are running Linux, then you are seeing threads within the Java process.

You will not get a single PID. Well, I tale that back. Never say never when it comes to Unix; you might be able to list the Parent PIDS only by messing with the 'ps' options. I have never done that myself, so I suggest, if you feel the need, to look through the man pages for 'ps'.

Re: concern about Apache + mod_jk + Tomcat cluster
Can you post the workers.properties file? I use equal lblweight (I think that is the name of the property) set to 100 for the 4 Tomcat instances. I have a nearly identical setup: twp Apache 1.3.27 server running on Redhat 7.3 load balancing across 4.0.6 Tomcat instances running on two Solaris 8 servers. We have no performance issues and I am using the default Processor settings in server.xml. We go through roughly 1 million hits a month.

But when I was load-testing the application, I noticed that there were lots of error message shown in the mod_jk file, although all the requests were dispatched to the tomcat servers and responded with 200. I then changed the 3 tomcat servers' configure as following: Connector className=org.apache.ajp.tomcat4.Ajp13Connector port=11009 minProcessors=1 maxProcessors=1 acceptCount=10 debug=1/ So now every Tomcat can only accept 1 request at the same time. I then sent 3 concurrent requests to the cluster: tomcat21, tomcat22, tomcat23. From the debug/log file, I think the mod_jk and tomcats are working like : 1, 3 requests reaches mod_jk, mod_jk sends requests to tomcat21 2, tomcat21 accepts the first one and rejects the other 2, 3, mod_jk logs errors in mod_jk.log, reports the tomcat is down or network problem. 4, mod_jk then sends the 2 to tomcat22 5, tomcat22 accepts 1 and rejects the other. 6, mod_jk again logs errors. 7. mod_jk sends the alst one to tomcat23, 8, tomcat 23 accepts it.

RE: failing installation server.xml file
A few hints on using RPMs: get to know the --query (or '-q') option to RPM. Specifically, you can list out all files installed by an rpm by typing: 'rpm -ql Package_name'. To get the exact package name (RPM usually requires the full version number), type 'rpm -qa |grep package_name'. For example, type 'rpm -qa |grep tomcat' to get the full package name. Then type 'rpm -ql tomcat_package_name' to get all the files installed. This will give you tthe layout of all the files installed. I would also suggest going over the stuff in /usr/bin. They are probably shell scripts. You can see what configuration files are pulled in from there. Having said all that, I do not use the RPMs for Tomcat myself. I use Solaris as my Tomcat platform. The binaries, as suggested earlier, are the easiest way to go.

I use it on my Apache error logs and to security checks on the access_logs. Easy to setup to boot. Here's an approach that may work for you: use log4j. Implement a TriggeringEventEvaluator (http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/spi/Triggerin gEventEvaluator.html) to do the regex or whatever rules you want to decide required a page from a log message. The evaluator will get every log message, including its complete stack trace and any details you want to add. You can use log4j's MDC (http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/MDC.html) to provide any details needed in order to decide whether the event merits a message to your page or not. Log4j comes with an SMTP appender that sends email and has all the logic you want: throttling and arbitrary rules for even evaluation. See http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/net/SMTPAppend er.html for details. Some more information about myself: I am a system administrator. The extent of my programmin g experience ends at Perl for System Administrators. So I have a questions that may sound dumb: Can you use these appenders as part of catching exceptions from within the Code? That is, if you catch a certain exception that is going to be logged, you set isTriggeringEvent on it and Log4J can then do what needs to be done? Log4j doesn't come with a pager appender right now. You could use a JMS appender to send events (that pass the triggering event evaluator's criteria) to a JMS server somewhere, as there are J2EE servers that can handle paging. Alternatively, you can write the pager appender yourself and maybe even donate it to us as a log4j contribution ;) Using the SMTPAppender to email it my pager would be plenty. This may seem like a lot, but it's really more work explaining the process than doing it ;) If I understand it right, you are right. This would be easily added to our existing exception handling.

Cookie Handling Question
We have some strange behavior going on, probably due to the strange setup one of our customers use. Before I get into it, some facts: Running Apache 1.3.27 with mod_jk 1.2.1 on two Redhat Linux servers talking to 4 Tomcat 4.0.5 instances. The Tomcats are running 2 per server on Sun Solaris 8 boxes using Sun's JDK 1.4.1. The Apache's are load-balancing to the Tomcats and we have a Cisco load-balancer in front of the Apache servers. Here is where it gets messy: the client is using IE 5.5 running on a Citrix terminal server. They are using multiple stations within a location and using the same account! So, user goes to station 1, logs in, does their business, then leaves the station without explicitely logging out of the app. They go to station 2, login, do their thing there then leavesetc. On top of this, there are other users who use the same stations but use different browser windows and different logins. The problem is that the user complains of having to re-login to station 1 after a couple of hours when he comes back to use the session he left open previously. Of course, with roughly 200 users at this site, we have only had 2 complaints of this behavior but we are doing due diligence to figure out what is going on. It looks like the browser is getting confused about which session cookie is the right one for the session and it sends the wrong cookie, thereby getting the invalidated session, please login again screen. Can anyone shed any light on how this sort of behavior might cause session timeouts because of mishandled cookies? How does IE 5.x know that a cookie is for this particular window, let's say, and not another? Are cookies tied to windows? Being a Unix sysadmin, I can only look out Windows (TM); I don't use them.

Are you sure you are not caching the web pages? Do you have caching on in the httpd.conf? Do you send the pragma-nocache in your HTML? Try changing the browser settings to always go back to the server and if you still get the old page, then look to see if Apache has caching on.

Re: Problems configuring Tomcat with Apache using mod_jk2
You need to JkMount the /examples in httpd.conf. Something like JkMount */examples blah where blah is the name of your loadbalancer setup in workers.properties. It would help if you post the entries you added in httpd.conf for Tomcat. Also include your server.xml file for more information.

Re: Tomcat security?
Plus, if one runs as a non-priviledged user account with no login privileges (i.e., locked account) and your permissions are correct, then only root and Tomcat can read the users file.

Slowness in Tomcat app
I am seeing a strange slowness on our QA tier. For some reason, this only occurs on this one tier (we have a production setup running, as well as a development playground). I have two Apaches talking to two Tomcats running on Solaris. They are running Tomcat 4.0.5. I can see no reason for the problem. Both Tomcats are up and running and listening on the correct ports. The only indication of an issue (which may or may not be related) is the following error in the mod_jk.log on the Apache side: [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (679)]: ajp_connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (1041)]: Error reading reply [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (1178)]: In jk_endpoint_t::service, ajp_get_reply failed in send loop 0 What does this error indicate?
