It might be better to move this to the Monitoring and Troubleshooting 
Tools forum [1] as it sounds like this isn't really an OpenJDK issue. A 
good start may be to run with -verbose:class to trace the classes as 
they are loaded. As this is a webserver maybe there are JSPs being 
compiled into classes and loaded. In that case the web container 
probably has its own class loaders then the classes may be unloaded in time.
