Assume that you use In-Memory OLTP in Microsoft SQL Server 2016. You try to recover to the last successful checkpoint, for example during database startup.

If a checksum mismatch with the In-Memory OLTP checkpoint files is detected, the recovery operation fails. However, SQL Server does not log the corruption information that has a severity level of 21 in the error logs, as expected.


This fix is included in Service Pack 1 for SQL Server 2016. If a checksum mismatch is detected during database recovery, error 3414 is written to the SQL Server error log and is assigned a severity level of 21.

Each new build for SQL Server 2016 contains all the hotfixes and all the security fixes that were included with the previous build. We recommend that you install the latest build for SQL Server 2016.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
