java.lang.OutOfMemoryError: PermGen space

[ilagi]

Hi,
I have a fresh OpenKM 4.1 installed on Windows 2003 Server and I'm the only user on it. When as an admin I check through the admin section (reports and stuff) after a while the Admin pages come up "The page cannot be displayed" and the server has a "java.lang.OutOfMemoryError: PermGen space" error message.
Any idea how to solve it?
Thanks

You need more memory, how much you've got in this server ?

modify run.bat or set environment variable JAVA_OPTS with values -XX:PermSize=64m -XX:MaxPermSize=128m

I recommend you take a look at google looking for "java jvm memory params" it's not trivial.

Thank you!

I already increased the memory allocation in the run.bat by changing
set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

to

set JAVA_OPTS=%JAVA_OPTS% -Xms256m -Xmx512m

but I didn't know that I can set PermSize too. I have set it to -XX:PermSize=64m -XX:MaxPermSize=128m and I tried to stress it and so far no out of memory error message.

Thanks again.

you can double it -Xmx512m too ( 1024 )

Hi,

I installed jrockit from oracle as my virtual machine to solve that problem. Far better garbage colllection too

[jllort]

I'm interested on /jrockit

could you put here some usage example here ?

Hi,

I just install jRockit as my JVM rather than the Sun JVM. I point my JAVA_HOME variable to the JVM path, set eclipse up using this and that it.

It can be downloaded from here: http://www.oracle.com/technology/softwa ... index.html

Thanks!
So far my issue went away by increasing the perm memory limit, but if we get more load it might appear again and then I will try your solution of changing JVM.
