Well, I was about to suggest that you blast the offending daemon with
at quit signal and see if you could get a useful "core" file, which
would at least give some clue as to what the daemon thought is was up
to.  Unfortunatly, the object is stripped, which makes debugging all
but impossible.  Still, you might give it a shot and send DEC the
data.  See "man signal" for things that will elict a dump, they probably
don't try to catch all of them.

Is there any hope of getting DEC to put unstripped objects on the
distribution tape as an optional file?  They seem to be limiting both
the customers and their own ability to diagnose problems by shipping
only the stripped versions...

We run 4 biod deamons here on a 785 2.2, and I haven't noticed the problem
you mention.  On the other hand, NFS use here isn't very intensive and
I might not even notice an occasional "lockup" as long as rn still
works good.   8-)  Oh yea, no PC-NFS (yet) and Sun-2's running 3.x,
a Sun-4 running that interiem release and a bunch of Amiga's running
Ameristar's NFS package.
