What happens if you try accessing Tomcat directly? (Assuming you have an HTTP connector configured.) I'd first poke around the problematic JVM with JConsole. You may find you're out of heap space, threads are deadlocked, one thread is in a loop, etc. If the problems do appear to be heap related, turn on -verbose:gc and see what's happening (and when it's happening). Make sure you have enough RAM to support the configured heap plus the rest of the process space; if you don't, you could be thrashing pages in and out. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
