Can you provide those after the issue thread dumps? Privately is fine if
you don't want to share them publicly.
Tomcat not responding to any requests is something that shouldn't
happen. I'd like to understand what is going on.

Mark,
I did take 3 thread dumps, but it was after the issue occurred. The thread
dumps just show threads in a waiting for work state. They are not doing
anything. They are not blocked. When I attach JProfiler to the JVM then it
points out that the threads were blocked during that short period of time due
to a database connectivity issue. Then Tomcat stops servicing requests. The
JVM is up though and has a valid process ID. I would have thought the threads
would be in a blocked state for a long period of time in this situation.
Regards,
William Crowell

Are there any logs I can enable to find out why the application server stops
accepting connections?
I'd suggest taking 3 thread dumps approx 5s apart when this happens.
Hopefully you'll see a bunch of threads waiting on the database and
where they are waiting will (hopefully) tell you why they are waiting
and point you towards a solution.
