Do you get the classic: "Shouldn't load state for %s when the connection is closed" or one of the "The database connection is closed" errors? In the first case you get the p_oid, which you can load from the database to give you some clue on what class it is. Typical problems include using plone.memoize decorators on things without knowing where exactly the cache is stored or as someone else noted registering persistent objects in the global site manager instead of the local one. The global one is of course just a module global data structure in the end.
