Please help with PermGen OutOfMemory error
After many webapp installs, I get this in my tomcat logs... Exception in thread ContainerBackgroundProcessor[StandardEngine[Catalina]] java.lang.OutOfMemory Error: PermGen space MaxPermSize=128m, but the errors still happen. I understand that this comes from apps not releasing all their resources. How do I track down what part of my app is leaving these resources behind? I'm hoping for pointers to tools/articles/blog entries - anything that'll let me isolate this problem (hopefully to a part of my code that I can actually fix as opposed to third party code I have no control over). thx andy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What is the version of your tomcat? 5.5 supposed to have resolved this issue by flush reflection cache when undeploy your web app. -Original Message- From: Andy Kriger [mailto:[EMAIL PROTECTED] Sent: June 27, 2005 12:12 PM To: tomcat-user@jakarta.apache.org Subject: Please help with PermGen OutOfMemory error After many webapp installs, I get this in my tomcat logs...

RE: Please help with PermGen OutOfMemory error
I did see this issue happened with my tomcat 4.1/5.0. After I upgraded to 5.5, I have encountered any outofmemory even after 100 hundreds deployments. Does your web app use struts? You can always clean up resource by adding Introspector.flushCaches(); in your context listener's contextDestroyed method. Otherwise, you will have to go through your web app carefully to find out if there is any memory leak. -Original Message- From: James Black [mailto:[EMAIL PROTECTED] Sent: June 27, 2005 1:25 PM To: Tomcat Users List Subject: Re: Please help with PermGen OutOfMemory error -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Phillip Qin wrote: What is the version of your tomcat? 5.5 supposed to have resolved this issue by flush reflection cache when undeploy your web app. I get this with 5.5.9, using jdk 1.5, under Solaris 8, when I copy my new beehive-based webapp into my webapps directory.

Struts is used in my beehive-based project (http://incubator.apache.org/beehive), but I will need to check if there is some memory leak otherwise.

Re: Please help with PermGen OutOfMemory error
As per tools - I think you can use JMeter. It gives u some pretty useful graphs and analysis. -Anoop On 6/27/05, James Black [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Phillip Qin wrote: I did see this issue happened with my tomcat 4.1/5.0.
