I have recollections from the v6.2-3 era, plus v7.3-2, of
the shutdown "hanging" while stopping queues.  I don't think
I was ever patient enough to wait 5 minutes to see if it
would eventually continue. :-p

We were running DCPS for a whole bunch of print queues.
IIRC, my solution was to be sure to stop all the DCPS
queues before starting the shutdown.  I also seem to recall
the hang being sometimes associated with a job in the queue
that was "waiting" for some reason.

Anyway, I'd recommend seeing whether stopping print queues
help this situation at all.
