Hi All. Sorry for the long delay - I've been waiting to make sure that the
fix(es) are actually working. Our machines decided to stop showing the
symptoms of the problem for a while, which made it slow going.
Thanks for all the many many replies, some even before I got my own message.
It seems that it may be a combination of two things, so first prize goes
to two people:
cdr@sachiko.acc.stolaf.edu (Craig Rice) sent me a beta sun4c version of patch
100330-01, which seems to partially solve this problem, and also fixes another
problem that had recently emerged. We have had no ill-effects from the patch
so far. Thanks Craig.
Mail me if you want this patch, and can't find it anywhere else.

Well, after applying the 100330 patch, the hanging was less frequent, but
did still occur once, so we tried not automounting /usr/share, and haven't
had any more problems.
Some of the other responses:
pjw@math30.sma.usna.navy.MIL (Peter J. Welcher) suggested increasing the
number of nfsd's in case they were getting bogged down with requests, and
adding more swap space.
stern@sunne.East.Sun.COM (Hal Stern) suggested trying the NFS jumbo patch.
keves@meaddata.com (Brian Keves) suggested trying the patch for bug-id's
1017518 and 1017893. (Seems this is only for 4.0.3 though).
mondics@tartan.com (Brian R. Mondics) suggested installing the lockd patch
100075-07. (We have already done this).
Thanks again to everyone who replied.
