Folks-
I've got an intermittent, recurring problem with NFS communication
on a couple of old DecStations running Ultrix, and was hoping that
I might get some help on this newsgroup. The two machines involved are
a Dec 5000/200 and a Dec 5000/240; Lets call them Click and Clack.
Click and Clack are NIS bound to my local domain and are acting as
file servers. During these problem times, network communication appears
to be quite slow with Click and Clack, but the network does not appear to
be busy or overloaded with Ethernet collisions. I don't see any
indication that Click and Clack become unbound from their NIS master.
When Click and Clack are acting up I get the following types of
error messages:
On Click or Clack:

Jun 16 15:31:35 margaret vmunix: NFS2 server clack ok
Assuming that I had a network problem, I tried the following:
- changing transceivers
- changing Ethernet cables
- changing Ethernet hubs
all to no effect. These bouts of NFS communication problems may be
correlated with times of higher room temperatures, but I'm not 100%
sure about that. Again, the network does not appear to be busy but
other machines fail to be able to contact Click and Clack for NFS.
I'd appreciate any help you folks can give.
Thanks.
Mike
