Consider the following scenario:
- You use Microsoft SQL Server 2016 or SQL Server 2017.
- Every few seconds you run a monitoring stored procedure that includes references to the Dynamic Management Fucntion (DMF) sys.dm_exec_query_statistics_xml, on a busy server.
- The query_thread_profile extended event is in use, or Trace Flag (TF) 7412 is enabled.
In this scenario, you may notice that random access violations occur.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
