Description (partial)

The Cisco NX-OS NTP process can get busy while processing older version NTP packets and may miss sending heartbeat messages. The NTP process gets restarted and continues as before. This doesn't impact the time synchronization functionality of NTP in any manner.

Observed with a repeated sending of NTPv1 packets.
