Yep - I reported seeing this kind of message a week or two back. Had a
machine which has /home , /usr mounted over NFS lock up because of it.
Keyboard was dead, couldn't log in with ssh or telnet, did respond to
pings. The messages I got consisted of

repeating every minute, along with "NFS server bison not responding...".

Funnily enough I was running rc5-linux-i486-bovine as well, and logging
its output to a subdirectory of my NFS-mounted home directory. Machine in
question is a cheapo pentium-100 running bog-standard 2.0.30, universal
NFS server 2.2beta25.

So far the problem has not reappeared but your report makes me think
the penguin maybe has some dodgy halibut in its larder :-)


Cheers,


Chris.
