Hmm, I don't think you mentioned what server you were using. It
wouldn't happen to be a FreeBSD one exported ZFS? If so, make
sure you have this patch in it:
  http://people.freebsd.org/~rmacklem/freebsd8.0-patches/freebsd8-nfsserver-estale.patch
(With it a stale file handle can result in EIO from a server exporting ZFS
 and that can make the client loop around, retrying the RPC.)

I'll take a look at some point.

It should work. This hints at a server issue.

Anyhow, I'll look at the dumps at some point, rick
