Re: Tomcat dies at 167M
It's possible that you are out of file descriptors. Find and use 'lsof' (ls open files) running it against that process. I've seen Java report OOM when it can not allocate a file because a File is nothing more than another object associated with the resource. If this is the case you will have to figure out where you are not releasing files or sockets and resolve the problem.

I would second that advice. the biggest factor for performance with XML is having a ton of memory. If the application doesn't use XML, I would suggest running some benchmarks with a variety of settings to see which works best. good luck peter On Thu, 23 Sep 2004 15:03:01 -0400, Fournier, Pete [EMAIL PROTECTED] wrote: You may be running out of stack, try upping the -Xss setting.

However, the docs do warn that the manager hasn't been heavily tested. Manager className=org.apache.catalina.session.PersistentManager minIdleSwap=-1 maxIdleSwap=120 maxIdleBackup=-1 Store className=org.apache.catalina.session.FileStore/ /Manager The above config should swap out any sessions which haven't been accessed in the last 2 minutes.

While the PersistentManager should solve your test case and problem of being swamped by new sessions, I feel that a better performing solution would involve a Manager which allowed a set number of sessions to be kept in memory (or even better, able to watch the amount of memory used by sessions) and when a preconfigured limit is reached, swap out the LRU session to disk. At some point it may also be desirable to expire a session early, too. Although unlsss you are being slashdotted or store a lot of data in your sessions, its easier to buy another stick of RAM for the server and increase Tomcat's -Xmx setting for most users. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Howdy, Thanks for the reply. Here is how I have the JAVA_OPTS set up(-Xmx256m -XX:+UseConcMarkSweepGC -XX:+PrintGCDetails) I wanted you to see this incase there is a problem with the concurrent GC collector. If there's a problem with the concurrent GC collector, I don't know of it. I assume that you've spent considerable time and research before selecting the current maximum heap and collector. It's not my, or anyone's on this list, place to tell you what GC settings to use. You need to: - Determine the expect load on your system - Determine how much memory your application requires to serve the expected load - Allocate that much memory to the JVM. If someone in your organization had done this analysis and come up with 256MB, then either: - His or her analysis was wrong - His or her analysis has become outdated as your application has matured - You have a memory leak. If you have a leak then yes, setting the heap higher just means a longer time until the server dies. This is why leaks must be fixed.

RE: Tomcat Dies
Rob, Sorry I'm late on this thread, I just noticed it. Actually, I have spent the whole last week or so chasing down some perceived memory leaks on Tomcat (in general, not in my application), and maybe you are hitting what I am hitting. What kind of load is the server getting? What I have seen is that if there is a reasonably heavy load for a short amount of time, you can have too many sessions in memory that have not yet hit their session timeout value, and so cannot be freed by the garbage collector. It is very easy to run out of memory well before sessions start being let go. As far as I can tell though, once the sessions were freed, the memory itself cleared up. (These comments apply to 4.1.28 BTW) Things you have in your control to solve this: 1) Make sure JSP's that do not deal with sessions have %@ page session=false % in them. If not, then a session object is created in every JSP, even if that JSP does not need it. 2) Define a Manager element for your context, and set the session activity settings. You CAN set maxActiveSessions, but the problem with doing so is that your JSPs come up blank as soon as you hit your max number of sessions, and continue to be blank until the sessions time out. So, you avoid an OutOfMemory and death, but you do not really service ANY new requests / sessions after that point. 3) Set your session timeout to a lower value. (in conf/web.xml, or in your application's web.xml) I have not yet played with this. It looks like the default value is 30 minutes. I was blowing up my server after only 7-8 minutes (with -Xmx256m), so I was not coming close to the timeouts. A lower value, of course, could have a negative effect on your user experience. 4) As it appears has been previously pointed out - higher memory maximums. I like to put it as high as possible and then see if the memory settles down at some point, leading me to my actual maximum. In my case, where every request was creating a new session, a higher maximum just stalled the problem, it did not solve it. 5) As it appears has been previously pointed out - play with GC. I haven't gotten this far myself. But, from what I can see on how the GC is acting, it is unable to free up the sessions, since they are still valid and have real references to them. I think playing with the new 1.4.x GC options would just make Tomcat be a little more stable as the memory fills up if anything, it would not (in my case) avoid the eventual death I was seeing.

Jeff Tulley wrote: What I have seen is that if there is a reasonably heavy load for a short amount of time, you can have too many sessions in memory that have not yet hit their session timeout value, and so cannot be freed by the garbage collector. It is very easy to run out of memory well before sessions start being let go. As far as I can tell though, once the sessions were freed, the memory itself cleared up. (These comments apply to 4.1.28 BTW) Jeff, have you tried a different session manager than the default (which is org.apache.catalina.session.StandardManager)? For example, org.apache.catalina.session.PersistentManager claims to be able to start swapping out inactive sessions to disk to save memory. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/manager.html A config like this inserted into your context should solve your memory issues with some performance hit if a session is swapped out to disk and is later swapped in. However, the docs do warn that the manager hasn't been heavily tested. Manager className=org.apache.catalina.session.PersistentManager minIdleSwap=-1 maxIdleSwap=120 maxIdleBackup=-1 Store className=org.apache.catalina.session.FileStore/ /Manager The above config should swap out any sessions which haven't been accessed in the last 2 minutes. You can also config a JDBC store. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Tomcat Dies
Hi There, It looks like there is a memory lieak in your code, do you have any listeners, and if so are you storing the session objects in a collection and not removing them from the collection when they are being invalidated.

RE: Tomcat dies
I've had this problem too in the past and our best (but definitely not
the most elegant) solution is to switch to C-shell before invoking the command.
Log on as root. (your root shell can be anything)
Create a user tomcat: useradd tomcat
Switch to C-shell: /bin/csh
Do something to the effect of
startme.sh
#!/bin/sh
su - tomcat -c ${START_CMD} /tmp/start.out
if [ $? = 0 ];
then
echo Tomcat started. You may close this window.
exit 0
fi
echo There was a problem starting up tomcat
exit 1
Run the shell script
The key here is to use C-shell when you invoke the start-up script. I have
a plain vanilla install of it running on solaris 8 (catalina 4.1.12) and
that works fine. I've had problems with 4.0.6 so take that for what its worth.
Hope that helps.

RE: Tomcat dies
tomcat conforms to true daemon properties that is dissociation from all file streams many a signals etc. On actual dissociation it should get bound to the inetd process of solaris. Make sure that your unix box is running nuder init status 6(which is normal wokring). Mostly there should be some other reason for its getting klled than this. we need to explore the exact reason and not be preoccupied with a thought that it is because it is not able to dissociate itself with input/output filestreams or terminal dissociation. Is there any other daemon on this solaris bos which runs fine, I mean does not die on closing the invking terminal.

Well, I'm running Tomcat with win2k without any problems. Try to update: - your JDK to 1.4 - are you running Tomcat under an admin account?

Ron Sahar, This is very simple error. It should not cause any other problems. What this massages are telling you are simply your apache server was not up while tomcat was tying to get a signal.

What does your .out file say? It should be in your logs folder. In Tomcat 4.0, its called catalina.out. Not sure what its called in 3.2.1.

Re: Tomcat dies immediately under windows
Edit startup.bat and change the command after ":start" to "call %TOMCAT_HOME%\bin\tomcat run %1 %2 %3 %4 %5 %6 %7 %8 %9" i.e. replace "start" by "run" Tomcat will now run in the same window, enabling you to read the error messages. re Jaap - Original Message - From: "Eric Armstrong" [EMAIL PROTECTED] To: [EMAIL PROTECTED]; "me" [EMAIL PROTECTED] Sent: Monday, January 01, 2001 10:52 Subject: Tomcat dies immediately under windows Note: Please use "reply all", as I am not subscribed at this address.

RE: Tomcat dies immediately under windows
Eric, I don't have access to a Win98 system so could you please test the attached tomcat.bat file. I've changed the java commands to use a -classpath argument. It works fine on WinNT but I'd like to get a test on Win98 before I commit the changes. -Original Message- From: Eric Armstrong [mailto:[EMAIL PROTECTED]] Sent: Monday, January 01, 2001 3:36 PM To: [EMAIL PROTECTED]; me Subject: Re: Tomcat dies immediately under windows More info: "tomcat run" works fine.
