You keep using the word "crash", but don't provide any evidence that the Tomcat process is actually terminating. It's highly unlikely that Tomcat is crashing - much more likely that your webapp is going to sleep for any of a variety of reasons, or just shutting down via a System.exit() call. Possible reasons include, but are not limited to, running out of data base connections (failure to close them), deadlocks, data at the wrong scope level, heap exhaustion... If the Tomcat process is still around, take a thread dump and find out where the threads are when things go to sleep. If you think the webapp really is running out of memory, prove it by running JConsole, and if shows heap exhaustion, run a profiler to find out where your webapp has a memory leak. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
