You may want to do a :linkcontrol @;status=all to determine for sure what sort of other traffice is going on with that subnet. I'm no network guru by any means, but I've run into the problem of another box (in my case running token ring -- ring around my neck, that is) that started broadcasting so much that regular traffic was timing out.
Just a thought.

Tom Brandt sent me the following email privately, but I'm going break
netiquette and post the answer I gave to Tom to the entire list, if for no
other reason than the advice is generally applicable to a wide range of
problems.

My primary advice still stands. Make your LAN as simple as you possibly can
first and work your way out from there. It's also important to remember that
software is never intermittently flaky; it's always deterministic in its
behavior. If you're experiencing intermittent failures, that failure mode has
to be because of the analog world that lives beneath the digital one.
Something is on the edge of working reliably -- and that can be anything from
a poor mechanical connection to an analog amplifier inside a chip that's
failing due to either age or heat.
However, I would suspect the cabling first. Here you often have non-soldered,
corrosion-prone mechanical connectors that you are trusting to make good
connections.
Best,
Wirt
