[cisco-voip] Another NTP problem

[Ed Puzziferri]

We had this issue on two different cluster when we upgraded from CUCM 8.5 to CUCM 8.6(2a)SU2.  The problem was bug CSCtw46611.  TAC accessed the root and restored the capture.txt file to fix the problem

You can try having TAC edit the 'tos maxdist' parameter.  It's been seen to help get NTP working in virtualized environments, though I haven't seen a good explanation of why it's needed only sometimes.
CSCue18813 is the CLI enhancement to let you configure it without root.

Afternoon all,

Our publisher appears to have an issue syncing NTP and I am getting the following error message:


SeverityMatch : Critical
MatchedEvent : Mar 22 16:42:05 CSCCMPUB user 2 ntpRunningStatus.sh: The local NTP client is off by more than the acceptable threshold of 3 seconds from its remote NTP system peer.  The normal remedy is for NTP Watch Dog to automatically restart NTP.  However, an unusual number of automatic NTP restarts have already occurred on this node.  No additional automatic NTP restarts will be done until NTP time synchronization stabilizes. This is likely due to an excessive number of VMware Virtual Machine migrations or Storage VMotions.  Please consult your VMware Infrastructure Support Team.

The publisher resides on UCS and sync's ntp with a switch on our network, the version is 8.6.2

Has anyone seen this before? According to the 'utils ntp status' command on the cli interface of the publisher the time is in sync.
