Help with "NFS server write failed"

[Ralph A. Shaw]

For the past few days, we've been getting messages like:

>NFS server write failed: (err=69, dev=0xf0648650, ino=0x2).
>NFS server write failed: (err=69, dev=0xf0722bf4, ino=0x2).
>NFS server write failed: (err=69, dev=0xf0648650, ino=0x2).

every few seconds on our Pyramid 9820's console.  Nothing obvious is wrong,
there are no local or remote file systems that are above 90% full,
but I am at a loss as to how to trace the dev= information to find
which system has the problem. 

We have a Pyramid 9820 running OSx 5.0-0824, mounting file systems (and
being mounted by) various PC's, Sun2's, Sun3's, Sun4's and a Mt Xinu
VAX11/785.

Does anybody know how to trace this information?
