ciped-cb at the remote site has disappeared, leaving the UDP socket
unattended (i.e. nonexistent) so that the periodic key exchange
("kxchg") attempt between local and remote ciped-cb is failing.

Contact with that site has already been lost by the time "kxchg -
refused" errors are occurring -- the cipcbN interface on the remote
end cannot continue to exist in the absence of ciped-cb.

Check /var/log/messages at the remote end to see if ciped-cb explained
why it was departing.

Set "maxerr -1" in the options file to prevent ciped-cb from exiting
merely because of temporary loss of connectivity to the far end.
