NetISR log messages.

We have a number of workstations connected via ethernet and with each
others' disks mounted via NFS. One of them is an HP9000/320 with HP-UX
6.2 running diskless, swapping on a HP9000/350. A third one is a
DecStation 3100, running Ultrix 3.0.

When I run the X11 window system on the 320's console, and access the
DecStation through an xterm (running on the DecStation), the following
problem sometimes occurs:

When a lot of output appears at one time in the Ultrix xterm, the
'netisr' daemon running on the 320 starts to output lines looking like
this on its console:

June 21  ..time.. Network NetISR Error 2002 pid [ICS]
  ** Unknown log event

These lines are sometimes repeated only some dozen times, sometimes
they don't stop until after ten minutes. Nothing I do seem to
determine when they stop. In particular, exiting the xterm window on
Ultrix and umounting its disks from the 320 doesn't work.

While these log messages are output, keyboard response on the 320 is
very sluggish.

The logging messages don't appear on any HP machine on the net except
the one I am running the X11 server one.

Not only xterm, but also Gnu Emacs 18.51 exhibits this problem.

Does anyone have an idea what these messages mean, and what can be
done about them (except not running Ultrix applications on a HP-UX X11
server :-( )? While they last, my workstation is next to unusable.

There doesn't seem to be a comp.sys.ultrix, which is why I'm sending
this to comp.unix.questions as well.

Thanks for any help.
