Hi All,

Collector is disconnected from MOM and we found the below log errors.

Both the time of Collector and MOM are in sync only.

[DEBUG] [Collector IPAddress@5001] [Manager.Cluster] Clock skew with collector IPAddress@5001 is 5727 ms
[VERBOSE] [Collector IPAddress@5001] [Manager.Cluster] MOM Failed to handshake with Collector IPAddress@5001
com.wily.introscope.spec.server.beans.clocksync.ClockSyncException: Collector clock is skewed from MOM clock by 5,727 ms.

The maximum allowed skew is 3,000 ms. Please change the system clock on the collector EM.

While your Collector and MOM may have the same time, i.e. 10:35 AM, it is the number of seconds that are off.  In the below message, they are 5.7 seconds apart.  So you would have to modify the times so that they are less than 3 seconds apart.
