| Doc Text: |
Prior to this update, the NTP daemon (ntpd) configured as a multicast client was not able to process multicast messages after an association with a multicast server had been created. As a consequence, the multicast client was repeatedly resetting the association with the server and it processed only unicast messages in the initial exchange. With this update, the described bug has been fixed, and the NTP multicast client now works properly in the described scenario.
