            <title>[SERVER-69777] Lock by dbName + UUID rather than namespace in cleanUpRange</title>
                <link>https://jira.mongodb.org/browse/SERVER-69777</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/d74e02997725825314644efdc19709bedd182461/src/mongo/db/s/migration_util.cpp#L423&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Locking by namespace in cleanUpRange&lt;/a&gt; may lead to orphan leaks.&lt;/p&gt;

&lt;p&gt;The next flow will result on an orphan leak:&lt;/p&gt;

&lt;p&gt;1. A rename was ongoing from collA ---&amp;gt; collB, which copies range deletion docs from collA to collB and keeps the collA ones&lt;br/&gt;
2. Step-down happened&lt;br/&gt;
3. Step-up happened, so range deletions were resumed&lt;br/&gt;
4. The resubmit wrongly happens by namespace rather than collection UUID&lt;br/&gt;
5. As namespace collA is not found, that range deletion docs are &lt;a href=&quot;https://github.com/10gen/mongo/blob/d74e02997725825314644efdc19709bedd182461/src/mongo/db/s/migration_util.cpp#L525&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;deleted&lt;/a&gt; &lt;a href=&quot;https://github.com/10gen/mongo/blob/d74e02997725825314644efdc19709bedd182461/src/mongo/db/s/migration_util.cpp#L303-L308&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;filtering by UUID+range&lt;/a&gt;, so range deletion docs from collB won&apos;t be processed.&lt;/p&gt;</description>
