When you say "lock up", do you mean the application stops responding, or the entire server stops responding, i.e. you can't get an SSH session or run any commands on the server? This is significant because the problem may not be related to Linux at all. I encountered a particularly embarrassing situation many years ago, during a demo of a Java application I wrote, when the application seemed to have locked up and the hard disk kept thrashing madly. This was due to the Java garbage collector. No messages will appear in /var/log either. The way to troubleshoot this would be to set memory parameters when invoking the 'java' command, or better yet, put a profiler in and see which parts of the software are the culprits. If you are sure it is not the garbage collector, then you should really check the server hardware. I once had a server motherboard that would lock up randomly. Eventually, I found out from a forum that it was due to a under-rated capacitor being used in the motherboard. It was a Abit BP6, if I recall correctly. The only motherboard that supported dual Celeron processors. >
