Are you restarting tomcat through the tomcat webapp or the command line?
From what I understand, restarting tomcat through the webapp does not
clear out loaded classes like it should so eventually it can lead to a
PermGen error. I would recommend starting and stopping the service
directly without the tomcat webpage. Also, this error can happen if
there is a dynamic class loader that is going haywire.

Folks --
I keep getting PermGen space errors when invoking openmrs (i.e.,
it has been deployed, now I'm going to the login screen). I have tried
various values of JAVA_OPTS, increasing from -Xms256m -Xmx256m
-XX:PermSize=1024m -XX:MaxPermSize=1024m, in units of 512m/1024m. The
strange thing is that Windows Task Manager does not show any change in
the "Commit Charge", it still peaks at 1630m of 3985m max, and my
physical memory doesn't go above 1291m of 2047m. Tomcat logs (for
256m/1024m) attached. I have done the Tomcat memory leak fix.
Any ideas?
Also, if anyone has any ideas about getting rid of leftover
sessions which didn't terminate properly due to lack of permgen space
and have made Tomcat unstoppable except by reboot, please let me
know. They are damnably persistent, deleting all the work and webapp
subdirectories didn't work. I've had to go so far as to uninstall
/reinstall Tomcat to get rid of them.
Thanks, Roger
