I had similar problem when I started Tomcat via SSH, and then I improperly
closed SSH without "exit" command. 

In some cases (OutOfMemory) memory is not enough to generate log (or CPU can
be overloaded by Garbage Collector to such extent that you will have to wait
few days until LOG will be generated) - but process cant' disappear...

Process can't simply disappear... if it is JVM crash you should see dump
file (you may need to set specific option for JVM to generate dump file in
case of crash)
