Here's the error: 

Task '*** Email address is removed for privacy ***' reported error (0x80041003) : 'The server reported a temporary error.  Error: 5102. Server. Xfs request 'SyncBinary' failed. Response code: 'DbError', server response: '720           0'

Can you help me fix this?  I've looked at the other posts but I can't see the solutions.  Thanks.
