I am receiving the below two errors in the Sharepoint ULS logs when running the timer job "Taxonomy Update Scheduler".

02/24/2016 02:19:01.68 OWSTIMER.EXE (0x1B74) 0x1B70 SharePoint Server Taxonomy 0000 Exception Failed to get restore event for content db 61898e78-cc40-4fc1-9e49-6b20e4aba10a.

Followed by below:

02/24/2016 02:19:01.68 OWSTIMER.EXE (0x1B74) 0x1B70 SharePoint Server Unified Logging Service c91s Monitorable Watson bucket parameters: SharePoint Server 2010, ULSException14, 044806dd "sharepoint server", 0e00178d "14.0.6029.0", 1f65804a "microsoft.sharepoint", 0e0017f9 "14.0.6137.0", 5136df43 "tue mar 05 22:16:35 2013", 00003e28 "00003e28", 000003c5 "000003c5", f2ce9ddb "spexception:810200bc", 30303030 "0000" 334b8111-1c55-4207-9b06-43ab902f27f6

These 2 errors are repeated for each of the content databases in the farm.

Managed metadata service has not been moved.

No site Collection has been moved.

No item has been moved regarding to search service or metadata service.

Please help me identity what needs to be done to fix the issue. Any help will be appreciated.

You should attempt to re-mount the Content Database using Mount-SPContentDatabase with the -ClearChangeLog parameter.

  • We are facing the exact same issue. Remounting did not solved the issue. Any other ideas, Trevor? - Thanks
