Yes, we have seen this problem but really aren't sure that it is
associated with NFS or the particular device that the data was being
written to (or some nasty interpay between the two).

I heard a explaination that a possible cause for NFS problems was that NFS
turns off check sums on the UDP packets it sends.  I verified that this is
indeed the case by looking at the packet headers.  I'd like to turn check
summing on to see if it helps.  Does anyone know how to do this?

I recently had to add a diskless Sun 3/80 client to a Sun 3/80 standalone.
I followed the documentation describing how to convert my standalone
system to an NFS server.  Everything went according to plan, except that
when I used the "setup_client" command, I had to put the swap space for
the client in "/usr/swap" instead of "/export/swap".  All went well
however.  The client boots up just fine, but occasionally reports "NFS
write error type 13" on the server during network transactions.  In
additon, "sundiag" on the client reports seek errors on FD 0.  "Sundiag"
on the server shows both drives pass diagnostics OK.  Basically, I'm lost
at this point.  Can anyone offer some insight??  I can't believe that the
disks on my server (was a standalone) are bad because they never exhibited
any problems up to now.  Please respond via email.  Thanks in
advance...........
