Hey
After server restart get the following error:
The Execute method of job definition Microsoft.Office.Server.UserProfiles.LMTRepopulationJob (ID 3945154a-ceeb-453e-89ea-7417dc8b227a) threw an exception. More information is included below.
Unexpected exception in FeedCacheService.IsRepopulationNeeded: Cache cluster is down, restart the cache cluster and Retry.
We already tried this solution (with no success): http://blogs.technet.com/b/mpriem/archive/2012/08/20/sharepoint-2013-preview-newsfeeds-showing-nothing.aspx
