FIX: SQL Server error log incorrectly cites logical processors when soft-NUMA is enabled

Applies to: SQL Server 2016 DeveloperSQL Server 2016 EnterpriseSQL Server 2016 Enterprise Core

Symptoms


In SQL Server 2014 Service Pack 2 and SQL Server 2016, soft-NUMA is configured automatically at the database-instance level when the SQL Server service starts. Soft-NUMA is enabled or disabled based on the number of physical cores. However, the SQL Server error log mentions logical processors instead of physical cores.

Resolution


This update is included in Service Pack 1 for SQL Server 2016.

Note After you apply this update, the SQL Server error log now contains the following message:

Automatic soft-NUMA was enabled because SQL Server has detected hardware NUMA nodes with greater than 8 physical cores.

Status


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