Look for the word "leak" in the Tomcat log files after undeploying one version. Those log lines give you hints, why Tomcat could not unload the classes. Unfortunately the solutions can be tricky, so for complex web applications it is not uncommon, that you migt have to live with those leaks, in other words provide more perm gen space and still restart every now and then.
