            <title>[SERVER-39464] Concurrent rename and shard collection causes shard collection to fail</title>
                <link>https://jira.mongodb.org/browse/SERVER-39464</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;While calling trying to check if there are any documents &lt;a href=&quot;https://github.com/mongodb/mongo/blob/7a7baa2539ec169335086e45c7d0b85ba7cdb877/src/mongo/db/s/shardsvr_shard_collection.cpp#L666-L672&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, it can hit the &quot;&quot;Executor error during find command :: caused by :: collection dropped.&quot; error and fail the entire command. Drop and shardCollection on the same collection are not supposed to happen at the same time, but it is possible with renameCollection (since rename never takes dist lock) and dropTarget set to true.&lt;/p&gt;</description>
