Dear HP3000-Listers

I have a strange HP3000 and NS/VT problem.

At various times over the last week or so, NS appears to 'hang'.  If we try
to connect with Reflection, we get a timeout and can't connect.  People who
are already logged in can continue working, sometimes, -- sometimes they get
disconnected and then cannot reconnect. Doing an NSCONTROL STOP to shut down
NS and then an NSCONTROL START to bring NS back up usually solves the
problem, but it disconnects all the NS sessions and forces them to reconnect.

We've been running a sniffer on the network, to see if anything is
generating a bunch of bizarre packets that could be cofusing NS, but we
haven't seen anything, but that could be because we don't know exactly what
to look for.

We're running MPE 7.0 express 1 on an 2-way 440Mhz N4000. SOS doesn't show
anything taking up an inordinate amount of resources, and I can connect via
Telnet fine during the episodes.

Has anyone else heard of anything like this, or have any idea of how we can
troubleshoot it more completely?

Thanks!
