[Dennis Heim]

I've seen this when you are pointing to multiple NTP sources and those sources are not sync'd.

2 NTPs "pointing to core switches" one shows as accessible and the other not accessible "still troubleshooting this part".

How many NTP servers do you have defined?

Dear all;

RTMT keeps giving me the below error "although time is synced":

At Thu Jun 09 21:56:14 CAT 2011 on node x.x.x.x, the following SyslogSeverityMatchFound events generated:
SeverityMatch : Critical
MatchedEvent : Jun  9 21:56:05 CUCM 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.
AppID : Cisco Syslog Agent
ClusterID :
NodeID : CUCM
TimeStamp : Thu Jun 09 21:56:05 CAT 2011
