registrars will not miss enough heartbeats to impute its death, and will
continue sending heartbeats. If the Meta-AMS transport mechanism is udp
and the restarted server uses the same udp port, then these heartbeats will
reach the restarted server. </span></font></p>

which it would ignore heartbeats from unregistered registrars (rather than
sending them a ‘you-are-dead’ message)? The grace period would
last long enough to allow the registrars to impute the death of the old
registrar and re-register with the restarted registrar.</span></font></p>
