Background: Doing the daily health checks on the SharePoint Servers we found a lot of Event Ids 7076, 6396 and 6482 in Application event logs, repeated by every 13 minutes.

Troubleshooting: We didn’t find relevance to this error as such on the Server. However, to stop their occurrences on the server, we did research on the Internet and found a Hot fix which talked about the same issue.

Resolution: Microsoft has released a Hot fix to fix this issue and it is available at: http://support.microsoft.com/kb/946517
