Customer recently upgraded a system from UCCX7 SP2 to SP4 per TAC recommendation. Today, the customer called saying that no calls were going to agents. In looking at the system, all the skills had been "removed" from the CSQ's, apparently following a server reboot.
The Skills in question had spaces in the name, so the skill "Store Support" was appearing as "Store+Support" when you attempt to add it back. However, it wouldn't "stick".
I restarted the config database services, and replaced the space with an underscore. This seems to fix it.
Has anyone else seen this behavior, or perhaps have any insight on the issue?
