The entire development group is working rotating morning vs swing shifts
and every night they are logging the zombies, then shutting down and
restarting the server.   Thank G-d my recently separated
"department" of
data management (me and one to-be-hired data analyst) is not responsible
for the functioning of the legacy database, so I don't have to be on that
assignment.

We have definitely established that when a user exits the application other
than by using the exit function (i.e. they use the close box or the
three-finger salute), their connection is not terminated, even when they
subsequently shut down their machine.   The Advantage guy we have
had onsite for the past week or so said this is a known problem.  I think I
understood that the problem is Novell's, but of course he would say that.

I think I heard them say they disabled the close box now, but we still have
zombies every night, so they must not have implemented your very helpful
information that I passed on although that's what they said they wanted to
do.

They are making a code review to see if they can speed up any of the
functionality that starts running slow and causes the users to kill the
app, which is all well and good, but I still think the first thing that
starts the snowball rolling is that the network bogs down.  I can't seem to
communicate that, I get "We ruled that out, the network doesn't cause
the connections to be held, the connections are held when the users kill
the app."
