I'm running IPT in Tomcat and experiencing PermGen memory errors.
From the Tomcat Manager, I can use "Find Leaks", and as suspected get:
"The following web applications were stopped (reloaded, undeployed), but their classes from previous runs are still loaded in memory, thus causing a memory leak (use a profiler to confirm): /ipt"
http://frankkieviet.blogspot.ca/2006/10/classloader-leaks-dreaded-permgen-sp... does a pretty good job of explaining _why_ this happens. Unfortunately, I can't seem to find part two which is supposed to tell me how to go about fixing it. His blog also only deals with memory leaks on redeployment, but this is happening any time IPT is running for a while, so IPT is leaking in ordinary use, rather than just at context initialization.
I'm going to try to find what's happening with a profiler, but I'm new to this...
