Is this the same server with the Wicket app you posted about earlier ? If so, you have a Wicket app that is storing the SessionFactoryObjectFactory on a page as a class member. Wicket stores each page a user has been to in the user's session. If the page has class members, then it serializes them and stores them too. I have seen this kind of thing happen many times before causing big memory usage.
Remove the Wicket app and run the Eclipse Memory Analyzer.
