Since we upgraded to Release 7.1.2_GA_3268.DEBIAN5_64 we randomly get Internal Server Error when trying to access the Admin Console. Sometimes it will work however about 70% of the time when going to the link https://mydomain.com:7071/ we get the Internal Server Error message.

This is the error I'm getting in the mailbox log:

Code:
2011-10-10 10:10:53,466 ERROR [btpool0-190://mydomain.com:7071/zimbraAdmin/] [] log - Error for /zimbraAdmin/
java.lang.OutOfMemoryError: PermGen space
Everything else is working fine. RAM shouldn't be an issue.

Any suggestions?
