Incorrect behavior of SESSION_CONTEXT in parallel plans
Queries that use the built-in SESSION_CONTEXT function might return incorrect results or trigger access violation (AV) dump files when run in parallel query plans. This issue occurs because of the manner in which SESSION_CONTEXT interacts with parallel execution threads, particularly if the session is reset for reuse. For more information, see the Known issues section in SESSION_CONTEXT.
