Matt Burdick gives some suggestions as to how to fix the problem ...
however, you may want to a little more searching to find the root
of the problem.

We've seen the same problems here, and finally tracked it down to a
broadcast storm occurring on our LAN.  It turns out that another
vendor's rwho product has a bug in it that causes it to forward the
rwho broadcasts.  This had the effect of causing a storm of messages
to appear on the LAN every time an rwhod broadcasted it's information.
Our solution was to not run rwhod, and everything has been working
fine since then.
