Hi,

Symptoms are total unreachability of the machine from anywhere but console,
failure of several components, such as sendmail etc. - I recall reading in
the BSD USENET archives of this problem - Am I right in assuming the value
of NBUF needs to be increased or is this handled trough maxusers only?
(which I've tried adjusting from 32 to 128 to 256 and back, same result)
It might be unrelated, but at the same time some 24 Win95 PC's were
dd'ing a 514mb image over the network*1 (total disk recovery), although
from a different host.
