only 2 percent permgen free

Hi,

we're running Confluence 5.4 Standalone on a RHEL 5 x86_64 (kernel 2.6.18-238.5.1.el5) with an external Oracle DB and our permgen space uses 250 mb out of 256.

Is this correct and healthy? As far as I know, 256MB is plenty for a normal permgen space.

Sincerily,

PermGen is used to store classes and usually quite static in size, but as you install new plugins it might grow. As plugins are OSGI modules and loaded dynamically.

6MB is very little... I suggest to increase it.

Hello.

I recommend you to increase the size of permgen as per How to Fix Out of Memory Errors by Increasing Available Memory. I suggest you to use a small increase (-XX:MaxPermSize=384m) not to have too much unused memory allocated.

Kind regards,
Alex.
