On just a very quick skim (you may want to verify to see I've got it
right), frame 30 shows the server returning a filehandle in a MNT reply,
then frame 48 shows the same client that got that MNT reply using the
same filehandle in an FSINFO reply, and getting an NFS3ERR_STALE
response.
Offhand seems like a server bug. Might conceivably happen if there was
some confusion whether the client was authorized to access that export?
