netstat will probably say the connection is open on both sides ---
otherwise the sockets would have closed.  It looks like both sides
still think the connection is open.  A firewall timeout is still
a possibility, but you'd have had to have a fairly long idle time
for that to happen.  Are any of the threads issuing commands that might
have run for very long intervals (tens of minutes)?
