>Description:
i observed that my nfsd sometimes returns EACCES or EIO
without any obvious reasons. i guess EIO was mapped from
EACCES by nfsrv_errmap.
i vaguely doubt that someone unexport the filesystem temporarily
(eg. sending SIGHUP to mountd, like mount(8)),
but there were no other activities on the server and
i couldn't find a culprit.
i have seen the same symptom with 3.99.2.
i have a packet capture taken on the server.

(see frame #193356-#193536. the client is linux 2.6.8.1.
broken checksums are due to h/w offloading.)
