FIX: Sort operator spills to tempdb in SQL Server 2012 or SQL Server 2014 when estimated number of rows and row size are correct
- Cumulative Update 3 for SQL Server 2014 SP1
- Cumulative Update 10 for SQL Server 2014
- Cumulative Update 8 for SQL Server 2012 SP2
Note After applying this hotfix, enable trace flag 7470 to make SQL Server consider internal data management memory overhead when calculating required memory for sort. This will avoid spills in the situation explained in the Symptoms section above. Note that this will increase memory requirement for sort queries and may impact memory availability for concurrent queries, therefore it is recommended to use the trace flag selectively.
