Fred,
I had something like this a while ago and in that instance I simply did
service nfs stop
rm -f /var/lib/nfs/etab /var/lib/nfs/rmtab /var/lib/nfs/xtab
service nfs start
I found references on other mailing lists to stale contents being
leftover in the /var/lib/nfs files after system crashs which is what
happened in my case and sounds plausible in your scenario.
Regards,
Stephen
