            <title>[SERVER-68193] Sharding DDL coordinator can lock itself out in distlock retry loop</title>
                <link>https://jira.mongodb.org/browse/SERVER-68193</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When the DDL coordinator acquires the local distlock, it stores it immediately to the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6e3c7116bfc02572b8842a914f1461b84f5a31f6/src/mongo/db/s/sharding_ddl_coordinator.cpp#L219&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;member variable&lt;/a&gt;. However, if the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6e3c7116bfc02572b8842a914f1461b84f5a31f6/src/mongo/db/s/sharding_ddl_coordinator.cpp#L221&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;acquisition of the non-local lock&lt;/a&gt; ends up asserting, it will keep the lock and try again. But when it retries, it won&apos;t be able to re-acquire the local dist lock because it is already taken earlier.&lt;/p&gt;</description>
