At least, it is not a sudden death.

Tomcat can be shut down by sending a certain string to port 8005 on
localhost (see the first lines of server.xml),  -> normal shutdown
or by sending a system signal that causes JVM to exit, or by calling
-> shutdown hook perform the shutdown

You can install a Listener and print a stacktrace when the stop event
happens.  The stack traces for the normal shutdown sequence and for
the shutdown hook will be different.

The Linux out-of-memory killer was already mentioned.

BTW, you are not alone: such a thread happens here every 4-6 months.
