+Queries that use the built-in `SESSION_CONTEXT` function may return incorrect results or trigger access violation (AV) dumps when executed in parallel query plans. This issue stems from the way `SESSION_CONTEXT` interacts with parallel execution threads, particularly when the session is reset for reuse.
+
+For more information, see the [Known issues](/sql/t-sql/functions/session-context-transact-sql#known-issues) section in `SESSION_CONTEXT`.
