[comp.sys.hp] HP 9000 woes

jstahlhu@hstbme.mit.edu (Julie Kozaczka Stahlhut) (05/21/91)

We're having a problem with an HP 9000/330 running HP-UX 7.03.  Sometimes 
people's telnet sessions hang and can't be recovered.   Typically, when
this is going on, I can ping the 9000 and find it alive, but no telnet   
sessions can be opened.    

Sometimes this resolves itself in a few minutes.  Other times, the machine
hangs so badly it has to be rebooted.  There have been times when the 
whole subnet it's on will hang and we can't telnet to the MicroVAX or 
the HP 3000 which are also on this subnet.  At first I suspected broadcast
storms, but everything on the net is set for 1's broadcasts, and the
subnet is isolated from our other building subnets via a cisco Systems
gateway server.  Rebooting the HP 9000 usually solves the problem right
away, even if every machine on the subnet seems to refuse to respond.

We're a little short of testing tools.  Can anyone recommend a test plan
for tracking this down?  Please respond by e-mail to :

                  jstahlhu@jenner.med.harvard.edu

 ... since my account at MIT is a guest account and I don't want to 
clutter up their system with my personal e-mail.


Thanks.
