Mind showing us a tcpdump of a copy that fails? I don't buy that
'server doing nothing bad' theory without proof.

Under a reboot, the server may indeed use ESTALE to deny access to
files. Normally you ensure that this doesn't happen by killing nfsd
before you unexport the mounts, and by re-exporting before you start
nfsd (see the NFS list archives about the 'exportfs' ordering bugs in
older versions of nfs-utils).

If the server does return ESTALE, then the client is perfectly correct
in assuming that is a fatal error.

Cheers,
  Trond
