Same problem here. Reloading such a tiny webapp generates memory leaks in the PermGenSpace (which is a non-heap space). Some libraries (apparently cglib) kept some Classloaders references and don't free them. This leads to an OOM : Out of PermgenSpace after some reloads (or redeploy) We have try to setup a "cleaner" ServletContextListener to force some cleaning job (Introspector caches) on contextDestroyed event, but it doesn't give any more results. Profiling instrumentations gave us some informations about what is loaded. But it's quite difficult to find the "guilty" source. I'm very interested in the following of this issue.
