Cause

Tomcat ran out of memory

Resolution

Allocate more memory to the tomcat process.

Edit the  $WEBCAMM/bin/catalina.sh and add the following line after the first 10 lines of uncommented text near the top of the file:

CATALINA_OPTS="-Xmx16G"

Stop and restart the tomcat process.  When you run a process listing you will then see the 16G as a parameter in the tomcat running process.
