This is highly likely as you are correct, we are not running with debug
turned on. It's on the list, but high availability for these services
has not permitted us to do this.
We know we have a problem with a third party vendor's code we have used
to build into the backend. It doesn't properly terminate when you run
their application from a shell, thus we are pretty certain this is
causing the problem with the backend processes not properly terminating
when our application terminates.

Thanks, as noted, that is the plan.
