            <title>[SERVER-73385] RenameCollectionCoordinator wrongly releases critical section for destination ns.</title>
                <link>https://jira.mongodb.org/browse/SERVER-73385</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;RenameCollectionCoordinator &lt;a href=&quot;https://github.com/mongodb/mongo/blob/183324bafa4753b04cd860b6f7110b8d604e87bb/src/mongo/db/s/rename_collection_coordinator.cpp#L243-L252&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;acquires the critical section for the destination ns if it is not sharded&lt;/a&gt;. Later, it &lt;a href=&quot;https://github.com/mongodb/mongo/blob/183324bafa4753b04cd860b6f7110b8d604e87bb/src/mongo/db/s/rename_collection_coordinator.cpp#L271-L274&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;releases the critical section if the destination ns exists&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This is not okay because it unconditionally releases the critical section on the destination ns, even if it is sharded. It could be that a migration is ongoing for the destination ns (because migrations have not been stopped yet, this &lt;a href=&quot;https://github.com/mongodb/mongo/blob/183324bafa4753b04cd860b6f7110b8d604e87bb/src/mongo/db/s/rename_collection_coordinator.cpp#L326&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;happens later&lt;/a&gt;) and is in the middle of the critical section. Then rename tries to release it an hits &lt;a href=&quot;https://github.com/mongodb/mongo/blob/50a3a7934a8f5239177ed373709427c9274fb54f/src/mongo/db/s/sharding_recovery_service.cpp#L434-L440&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this tassert&lt;/a&gt;.&lt;/p&gt;</description>
