OutOfMemoryError: PermGen space

[ncmuthu2002]

Hi,

      I am using alfresco 1.3.0 with tomcat 5.5. When I am using  on the alfresco page, I am geting error like "OutOfMemoryError: PermGen space". When I am clicking on some folder or adding a file or creating group, this error is coming. I tried increasing the Heap size. After that also the same problem occurs. I have attached catalin.out. Can somebody help me on this.

Interesting, I've only seem this message when running in JBossPortal (which includes JackRabbit which outputs this message all the time…). Try adding this setting to your JAVA_OPTS variable:

-XX:MaxPermSize=128m

Thanks,

Thanks for your reply. Now the "OutOfMemoryError: PermGen space" error is not coming. But I am facing a different problem after this. I leave the tomcat server on  in the night. When I try to login in the morning, I am getting a error in the browser like,

=========================================
Note : This error happens only once. If try to reload the page it works well.

Can you give us a idea how to resolve this.

Thanks,
Muthu.
