Hi Doreen,
Please make sure that-XX:MaxPermSize is set to at least 512MB in Tomcat's
bin/setenv.sh file.
Thanks,
Anand

Subject: [Building Sakai] Perm Gen Space Error
Good Morning,
Who has some suggestions to resolve a PermGen space error issue we continue to
have on our server? Seems we can keep our server up for two weeks straight
without it crashing on the following error. It's so bad we've started to keep a
calendar and log the crashes.
One of my co-workers has been working on this and has implemented many of the
suggestions but nothing has been a fix yet. We're hoping for new, not yet tried
solutions that will be our final fix. I've included a bunch of information
below that may or may not be helpful.

This information will automatically be included in your bug report.
