I'm surprised that this is such an old issue! So, if I understand the discussion correctly, Tomcat redirects stderr into stdout_XXX.log, right? Strange though, that I couldn't find my stack trace when I ran exception.printStackTrace(). Either this goes to yet another place, which I can't believe or I must have completely missed in, which I can't quite believe either ;) 1. System.out is buffered. So it might get stuck in the buffer. (Just saying. Have not tried to verify whether it is truth). System.err.flush() should help. good point. But in my case it should have come eventually :) 2. If you used swallowOutput=true in the context configuration file (it is false by default), then it will be written to the log file of the Host, i.e. into localhost_* log. I checked that, swallowOutput is set to false.. I will do some more tests, it is still a mystery to me...

realm authentication no longer works through apache - mod_jk after upgrade still works via straight tomcat 8080
Hi- I recently upgraded tomcat, apache, apr and mod_jk. Now when I access via apache -- mod_jk on port 80 ie. www.mydomain.com/myappname/ the Velocity login page displays fine but after hitting the login button /admin/j_security_check displays in the URL and a blank page is displayed. .do and .vm pages on port 80 that do not require authentication display fine. When I bypass mod_jk by accessing via port 8080 users can authenticate, with no problems and the applications function properly. I've pasted log and configuration information below.

As a result the apache worker process is bound to the sleeping tomcat processor (aka thread), andI assume that each following request to the same servlet will produce one more sleeping processor and one more sleeping worker, until there are no more workers or processors left, whatever comes first.

They are apparently related to the same issue, and it is confusing to follow 2 separate threads.

Do you mean that the number of apache processes increases? If so could it be, that your (or whosever) MUXServlet is sleeping (SLEEPING?!) in its post method. As a result the apache worker process is bound to the sleeping tomcat processor (aka thread), andI assume that each following request to the same servlet will produce one more sleeping processor and one more sleeping worker, until there are no more workers or processors left, whatever comes first. But to answer it definitely, one would need to see the code of the MuxServlet (or the complete thread dump). regards Leon P.S. Side note, I can barely imagine any reasonable grounds for a servlet to call Thread.sleep in a doPost/doGet method. I would like to know what is causing for apache process to go high. Is it porblem in a backend tomcat server or it has to do something with apache itself.?

In 'the other thread' there is still the question open of why there is Thread.sleep() in the MuxServlet. Can be a reason for a lot of open connections in the httpd server.

Maybe the first things to do : 1) do not post files as attachments in this list. Mostly, the server strips them. Instead, if we ask you for some text information, do a copy-and-paste, and paste the content directly in your email to the list. Also, when you copy contents of files here, please remove the comments, and any private information such as internet hostnames or passwords. 2) tell us what the platform is (O.S.) 3) if you can, also tell what exact version of the mod_jk moduile you are using. You should be able to find this in the message that Apache httpd prints in its error log when it starts. 3) in the configuration of Apache httpd, there must be configuration lines starting with Jk... Copy them here. 4) copy here the full content of the workers.properties file (comments removed) 5) in the Tomcat conf/server.xml file, there is a Connector element with a protocol=AJP. Copy this Connector element here. 6) if the platform is Unix/Linux, execute the following command and copy the result here : apache2ctl -V 7) if the platform is Unix/Linux, go to the bin directory of Tomcat, execute the command version.sh and copy the result here. With the above, we will get a much better idea of your configuration, and of what to ask next. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

If you mean that the CPU is experiencing high load, then the thread

Why? Because Thread.sleep doesn't use CPU time: it blocks waiting for a
signal from the CPU saying that it's time to wake up. It's still
possible this is the problem, if the Thread.sleep() call is in a loop
without much of a sleep, like this:
while(true) {
Thread.sleep(1);
}
That would peg your CPU.
Why not look at the code in com.ericsson.eai.b2b.MUXServlet.java at line
506 and see what's going on?
Is it porblem in a backend tomcat server or it has to do something
with apache itself.?
That depends on what the problem is :)
tomcat version :- 5.5.9
You need to upgrade, but that's not causing your CPU load.
You need to use a tool such as top to find out which process is using
all your CPU: once you determine if it's Tomcat (process will be java)
or Apache httpd (process will be apache2 or httpd depending on your
system).

The configured format will tell you, what the entry means. Likely it is either the name of the virtual host, or the value of the host header the client sent. Cleartext: this is requests being processed by your Apache server. The client sends these requests to erib2bdev.ericsson.net and they are received by your server. Or you configured your server to carry the name erib2bdev.ericsson.net. For details see: http://tomcat.apache.org/connectors-doc/reference/apache.html and look for JkRequestLogFormat in that page. The use of that directive is no longer recommended, because it is easier to include request log information into the usual access log via mod_log_config. Look for mod_log_config in the same page. I am not sure what does it mean when the name erib2bdev.ericsson.net is not refereed anywhere in my apache and tomcat configuration files and not even in workers.properties file. Can anyone help me torubleshoot this issue? Furthermore this might not have to do with your issue, namely that you think the number of Apache processes is to big. From the other thread you posted containing the Java thread Dump excerpt we think that the reason for the growing number of processes is, that your MUXServlet doesn't handle the request and instead enters sleep. To make this assumption a fact, you would need to tell us, whether there are many threads in the same dump, that have the same stack (sleep in MUXServlet), more precisely how many and what the names of the threads are. If you find let's say 200 of those, then you are close to an explanation. Finally you have to do more than one dump to understand, whether the sleep() was only lasting for a short time, or it is happening all the time. Then you have to start talking to the developers of the MUXServlet showing them those dumps.

I'm still digging, but I thought I'd send this along to the mailing list while I try to decipher the mod_jk code. We're using tomcat-connector 1.2.31 on apache 2.2.17 on a Linux system. Log file is at this URL: http://www.moonteeth.com/~dopey/tomcat/mod_jk.log http://www.moonteeth.com/%7Edopey/tomcat/mod_jk.log The worker configuration consists of a load balanced worker with 9 workers (tomcat1-9). At any given time, usually only one tomcat is in use. In the case of the log, all the workers are in recovery state (apache started before tomcat, and someone hit the page so the tomcats are all down). In the log file the requests 5356:1146444096 /Windchill/servlet/WindchillAuthGW/wt.httpgw.HTTPAuthentication/login and 5357:1138932032 /Windchill/servlet/WindchillGW/wt.httpgw.HTTPServer/ping come in almost simultaneously. 5357:1138932032 completes first and picks up tomcat1, recovers it and uses it. However 5356:1146444096 never tries worker 1. 5357:1138932032 grabbed worker 1 before 5356:1146444096 does, and by the time 5356:1146444096 gets the worker list, it never bothers to try tomcat1, just tries all the other workers. As I said, I'm still digging at the mod_jk code to try to find out what's going on, but hoping that maybe someone else has also seen this problem. I can't reproduce this on my system unfortunately, and it's quite intermittent.

Re: Q? is it possible to patch an existing Tomcat server install in order to advance it 'in place' to a higher version?

You could probably just unzip a new binary package on top of your old one: anything new would be updated, but you might also inadvertently overwrite customizations you've made to configuration files, etc. It's best to take Pid's advice and do a side-by-side. The advantage of that is being able to roll-back with very little effort. Look into using CATALINA_HOME/CATALINA_BASE. With that configured, it took me 5 mins to upgrade the ASF test Jira instance from 6.0.29 to 7.0.6 and most of that was waiting for Jira to start (twice because I forgot to clear out the work directory the first time). Also +1 to eating one's own dogfood. :) p - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org 0x62590808.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature

Re: Possible race condition with mod_jk + multiple workers in recovery mode
I'm not sure, but it looks like the service() function in jk_lb_worker.c calls puts a recovering worker into the JK_LB_STATE_PROBE state and then doesn't set it to JK_LB_STATE_OK until after the end-service() call. I think this allows a second thread to come in, and since JK_WORKER_USABLE() returns false because of the JK_LB_STATE_PROBE state it never tries to use that worker and the second request thread completes, then the first request completes and finally marks the worker as JK_LB_STATE_OK. Still working on a reproducible state to debug this in, but does this sound like a possible problem or am I mis-reading what the end-service() call does here: service_stat = end-service(end, s, l, is_service_error); Thanks, Andy On 01/11/2011 12:08 PM, Andy Wang wrote: I'm still digging, but I thought I'd send this along to the mailing list while I try to decipher the mod_jk code.
