you are running in client mode this could be one reason why crashing. try this:

JAVA_OPT="-server -Xms 0.25*RAM -Xmx 0.75*RAM"

where RAM is you physical ram from your server

Show us your crash stack trace. Also I would recommend to use the latest Tomcat.

Check the logs under tomcat/logs
Try to increase the heap space
Try to enable the debugger

If possible,try to upgrade to Tomcat 6...
