Many thanks for few people who responded with real answers. This is
really great. Eventhough I couldn't rule any solution, my gut feeling is
that latest kernel jumbo patch fixes the problem. After applying the
patch we haven't seen the problem so far.

I wanted to let you know that I had a similar
problem with a SS1000 with a quad ethernet card. It turned
out to be a bug in 2.4 related to the quad ethernet card
(that to my knowledge has'nt been fixed yet). And the
workaround is to put:
set nfs:nfsreadmap=0
in the server's /etc/system and reboot. Hope this helps.
