We had an unexpected shutdown of the Web Viewer task. Not an abend, but what appears to be a 'clean' shutdown in the middle of the day.
Insufficient heap size. java/lang/OutOfMemoryError
Database problems with many error messages. There have been no problems at all since the Heap Size was increased in the Tomcat task.
Set IJO="$IJO -Xms1024m -Xmx6144m" (it was 4096m).
