I always had a lot of problems with a server developed in house in a old job. This problem smells like them, JVM crashes, but you need to investigate better.

You can starts looking for hs_err_pidNNNN.log files across file system. -It can be into JAVA_HOME folder used by your Tomcat or TOMCAT_HOME directory.

find / -name "hs_err_pid*"

Select all hs_err_pid files found with approximated date and time with Tomcat fall. After analyse them following the Troubleshooting Guide for Java SE. Give special attention for "C.5.4 Heap Summary" session.

In my case the crash was caused by "lack perm gen". The solution was increase this memory area with -XX:PermSize and -XX:MaxPermSize parameters.

Good luck!
