Time Sync causing Cluster Issues

Time Sync causing Cluster Issues

Issue:

The customer is having issues with the cluster going out of sync causing various issues.

Examples:
webRDP giving and Unknown Error
Users unable to authenticate
UW just running slowly in general

Customer will rebuild the cluster, only to have it go out of sync again.


Solution:

One of the second leading cause of the cluster going out of sync, behind communication issues between the loaders, is not having the UW servers in time sync.  The cluster relies each loader being within 30 seconds or each other, to properly pass the clustering information back and forth.

The best way to do so, is to set all the servers to use the same reliable NTP source.

The NTP Pool Project is a very reliable NTP source:
