OK, worth a try.

Indeed. But the machine which gets the most problems serves Acorn Access to
the rest of the network, and also hosts a backup caddy (for itself and also a
number of !Packdir image files- created elsewhere, but copied onto the caddy
once per week. It is copying these image files onto the caddy over the
network from the linux box where they are first saved which most often causes
the freezes.)
Being a server, it runs fewer applications than any other machine on our
network, but yes, still far from 'clean.'
Another source of occasional problems is client/server-ing a Datapower
database hosted on that same machine. No apparent crashes at either end, but
the Access link goes down and can only be restored by a restart. Of course,
this isn't necessarily your etherk problem either, because the other network
traffic to the server is not generally affected AFAICS.
