--- Comment #6 from Rick Macklem <rmacklem at FreeBSD.org> ---
I am not a jails guy, so I don't know if that was a factor.
W.r.t "..BROKEN MIDDLEWARE.."
It refers to a case where something between the NFS server
and client tries to cache Getattr replies, but doesn't get
it right.

Try testing where the NFS client connects to the server
without anything like a cisco switch in between. Just a wire
or a really dumb no frills switch.

Also, try an NFSv4 mount, since the NFSv4 RPCs are much
harder to cache and send replies.

If the problem persists, add another comment to this bug
report and we can try some other stuff.
(The error is generated because a file's fileno has changed
 and that should never happen.)
My guess is that having the two mounts for the same file
system has somehow triggered the generation of a bogus cached
reply.
