Nope, the machines have been rebooted...

They have indeed very old files there that were removed.

No, that not the case. But I can see why it would wreak havoc.

Anyways, this is what I did:

 - I shut down all boxes interacting via NFS.

 - When booting them up, I switched to single-user mode and:

     * wiped /var/lib/nfs/mtab

     * removed any files in /var/lib/nfs/sm{,.bak}

And we'll see if the message shows up again.

Phil.
