            <title>[SERVER-74881] Delist opCtx if sessionWorkFlow errors between dispatchWork() and acceptResponse()</title>
                <link>https://jira.mongodb.org/browse/SERVER-74881</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There is currently a race with shutdown in &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L760&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;SessionWorkflow::_scheduleIteration()&lt;/a&gt;. &lt;/p&gt;

&lt;p&gt;As part of &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L769&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_doOneIteration()&lt;/a&gt;, the opCtx for each scheduled workItem is created as part of &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L687&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;dispatchWork()&lt;/a&gt;, and the opCtx is expected to be destroyed as part of &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L701&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;acceptResponse()&lt;/a&gt;, which is called in a &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L752&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;continuation&lt;/a&gt; of the above dispatchWork() call.&lt;/p&gt;

&lt;p&gt;However, it&apos;s possible that we shutdown after calling dispatchWork() and before acceptResponse(), which means we enter &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L738&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;cleanupSession()&lt;/a&gt; before delisting the opCtx. As part of cleanup, we eventually enter &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/transport/session_workflow.cpp#L337&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;killExhaust() which will create a new opCtx&lt;/a&gt; to issue the killCursors command. This causes a &lt;a href=&quot;https://github.com/10gen/mongo/blob/e55b12deea15dee85691c92121d956c000c7008e/src/mongo/db/service_context.cpp#L283&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;tassert&lt;/a&gt; to fire since we would be trying to create a new opCtx while one is already registered. &lt;/p&gt;</description>
