SharePoint - Sync User Provide to Site Collection

Sometimes the sync between the User Profile service and the site collections get disconnected and updates to the site collection do not get synced.

Running theses stsadmn commands and the timer job usually fix the problem. The first commend is not necessary but reports the current state.

Stsadm.exe –o sync –deleteolddatabases 0
