A while back somebody mentioned that if you continuously redeploy a web application, the symptoms you are mentioning occur. This is because of all of the objects that are stored in the "permanent generation" memory. This permanent generation runs out of space, even though the new generation and old generation heaps still have room to grow. (The permanent generation's size is a fixed percentage of the total memory). I do not know if this is something that can or is fixed in the most recent builds and latest major version (5) of Tomcat.
On NetWare, we have a view into the memory where we can see how big the perm gen is and what percentage of it is allocated. I do not know if such a thing exists on other platforms though. If it does, I certainly have not yet found it. Searching the archives (at http://marc.theaimsgroup.com ), it looks like it could have something to do with the classloader layout of your application: http://marc.theaimsgroup.com/?l=tomcat-user&m=107046034505454&w=2 >Although the possibility of a memory leak (sorry--unintended object >retention) has not been completely ruled out (yes, I'm running the >applications through a profiler), I'm quite puzzled that this problem >would occur when, by all indications, memory use is nowhere near the >limit.
