nfsd going crazy

[Robert L. Krawitz]

One of your clients has something running hard, very likely in an infinite
loop.  We had a server (4/280) that for a month was running very slowly
(no one particularly complained, at least not in earshot of me).  I
finally took a look at the situation, and discovered that a 3/140 had a
csh that had been looping all that time.

Unfortunately, tcpdump doesn't work on 4.0; that was (still is on our two
servers still running 3.5) a really useful tool for things like this.
Modulo that, you have to play around with netstat -r, rup, and other
random tools of that nature.
