| Explanation | |
| The SQL Server process could not release a latch because it no longer owned it. This could happen because a user canceled a query or there was a data integrity problem. This indicates that an internal error occurred in SQL Server. Contact Microsoft Product Support Services (PSS) for further assistance. | |
| User Action | |
| Contact Microsoft Product Support Services (PSS) to report the issue. If there are any data integrity-related issues, you should see additional errors in the error log. Refer to the description of that error for information on how to proceed. | |
