At a customer site I got EventID 12330 LS Server stating that abserver worker process failed to initialize itself. A quick google search lead me to this forum article:http://social.technet.microsoft.com/Forums/en-US/ocsaddressbook/thread/6365091e-ec34-46cc-b9f7-e362b9084bb3
There MVP colleague Johan Veldhuis found a cause of this problem. The cause was that the SQL database being backed up when the Addressbook was being generated resulting in low responce time and therefore the process did not complete its update. The addressbook is being generated at 01.30 default every night, and if it can not update we will see this kind of behaviour
- Use the Set-CsAddressBookConfiguration cmdlet to change the generation time
- Set-CsAddressBookConfiguration -RunTimeOfDay 23:00
- This will set the addressbook update to happen at 11 in the night to ensure no SQL backup overlap
