Sometime during the night rpcbind on my server apparently quit
working correctly. It appears that my tcp4/udp4 services went down
and can't start back up (network restart, etc. or complete reboot).
Remote and local NFS mount attempts see :

 mount_nfs: rpcbind to nfs on server: RPC: Program not registered

No config info was changed. The server had been in use and these
services just disappeared. Nothing apparently logged.  What broke
tcp4/udp4 and how do I get them restarted?
