Re: help to solve 'OutOfMemoryError'
Hi, I don't have any idea about the Linux environment. But, I got a OutOfMemoryError due to permgen space on windows/Tomcat5.0.30 environment and this is what I have done. set CATALINA_OPTS in catalina.bat if Tomcat is started using startup.bat set CATALINA_OPTS=-Xms128m -Xmx512m -XX:MaxPermSize=256m and if Tomcat is started as a service then JVMOptions is set in service.bat "%EXECUTABLE%" //US//%SERVICE_NAME% ++JvmOptions "-Djava.io.tmpdir=%CATALINA_BASE%\temp;" --JvmMs 128 --JvmMx 512 Hope this helps.

RE: FW: Tomcat upgrade: 3.3.1 --> 5.0.28, hang up after running 1 or 2 days
Hi Monica, For the past few days I was working on PermGen/Heap space issues. Last night I cold fix this problem after a very long research. I was getting OutOfMemoryError due to PermGen space. I have set -XX:MaxPermGen parameter in my service.bat. Here is the code sample : "%EXECUTABLE%" //US//%SERVICE_NAME% --JvmOptions "-Dcatalina.base=%CATALINA_BASE%;-Dcatalina.home=%CATALINA_HOME%;-Djava.endorsed.dirs=%CATALINA_HOME%\common\endorsed;-XX:PermSize=128m;-XX:MaxPermSize=256m" --StartMode jvm --StopMode jvm This is the configuration setting if you are starting Tomcat as a service. FYI : My Tomcat version is 5.0.30. Note: Must be very careful with the syntax. Hope this will help you.

Upgrading to 5.5.x is an idea. Another one is about PermGen space, suggested by Chunk in earlier message in this thread. So far I don't have confidence that TC5.5 can fix the problem my TC5.0 has. I will try to tune up PermGen space parameter and see how it goes. By following Chunk's email, I am googling how to tune up PermGen parameter. I will do followup for progress.

It hang up every 1 or 2 days during weekdays, depending on web server traffic. Unfortunately, I don't know enough to be able to help you here, but since 5.0.28 isn't working anyway, have you considered upgrading to 5.5.x to see if that would fix the problem?

HI George, Thank you for the reply. I tried to use this option in my service.bat but when I start the service its giving error.(FYI: I am using Tomcat 5.5.12.) Then I set in CATALINA_OPTS but its not taking the PermSize/MaxPermSize values. Thank you, Aparna.

I am working with 64 bit java on Windows 2003 and 64-bit AMD Opteron processor with 16 GB RAM. I am getting OOME due to PermGen space.

I checked the windows registry and these parameter values are not inserted. Do you have any idea like what might be the problem and how to fix these issue ? Any help would be greatly appereciated.
