            <title>[SERVER-79202] PinnedConnectionTaskExecutor can hang when shutting down</title>
                <link>https://jira.mongodb.org/browse/SERVER-79202</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;PinnedConnectionTaskExecutor creates a lambda with a shared_ptr to itself here: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4ff092d683be418230ef28fa3f3c81833b82c570/src/mongo/executor/pinned_connection_task_executor.cpp#L323&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/4ff092d683be418230ef28fa3f3c81833b82c570/src/mongo/executor/pinned_connection_task_executor.cpp#L323&lt;/a&gt; that can extend the PinnedConnectionTaskExecutor&apos;s lifetime (the lambda is scheduled to run on the ThreadPoolTaskExecutor the PinnedConnectionTaskExecutor proxies over) &lt;/p&gt;

&lt;p&gt;If the shared_ptr stored in that lambda is the last reference to the PinnedConnectionTaskExecutor, the PinnedConnectionTaskExecutor will be destroyed upon that lambda&apos;s destruction. This can result in the destruction of the PCTE&apos;s shared_ptr to the underlying TPTE, which will call join on that TPTE. However, because the lambda is executed on one of the TPTE&apos;s own threads, we violate the TaskExecutor::join contract and may hang (we are stuck waiting for our own callback to finish). &lt;/p&gt;

&lt;p&gt;This should only be a problem in tests, because the only production-use of PinnedConnectionTaskExecutor is TaskExecutorCursor, which uses the mongotExecutor as the underlying TPTE. A shared_ptr to that object is stored in a ServiceContext decoration and is only destroyed when the ServiceContext is.  Since search is mongod-only, and we don&apos;t destroy the serviceContext ever in mongod in production (and we destroy all user operations/clients first), it shouldn&apos;t be possible for any PCTE callback to have the last reference to the underlying TPTE. &lt;/p&gt;</description>
