We use automatic restarts on OutOfMemory errors and it works fantastically. I don't do it the way described here, though. I use the JVM's -XX:OnOutOfMemoryError option. I add the following to CATALINA_OPTS:
-XX:OnOutOfMemoryError=/usr/sbin/restart_tcserver ...which restarts tcServer whenever an OOME occurs. Unfortunately, it doesn't produce a stacktrace (it calls your script instead). But that's okay in my case. I just want to make sure the server gets restarted. We had one of these a while back, so I know it works fine (the restart script also sends me an email--including "top" output--letting me know what happened). Thanks!
