            <title>[SERVER-43727] Yield locks on secondaries while waiting for two-phase index builds to commit or abort</title>
                <link>https://jira.mongodb.org/browse/SERVER-43727</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Because we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/81deec4580a95475ed906ec5840290e003663b38/src/mongo/db/concurrency/d_concurrency.cpp#L206-L210&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;upgrade all IX locks to X locks on the &quot;admin&quot; database&lt;/a&gt;, two-phase index builds on secondaries that are &lt;a href=&quot;https://github.com/mongodb/mongo/blob/81deec4580a95475ed906ec5840290e003663b38/src/mongo/db/index_builds_coordinator.cpp#L998&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;waiting to commit or abort&lt;/a&gt;, will deadlock waiting for a replicated &quot;commitIndexBuild&quot; or &quot;abortIndexBuild&quot; oplog entry. These replicated commands&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/81deec4580a95475ed906ec5840290e003663b38/src/mongo/db/repl/oplog.cpp#L1553&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;take a database IS lock before they are applied&lt;/a&gt;, and will be unable to complete, preventing the index build from completing, but also stalling replication.&lt;/p&gt;

&lt;p&gt;The simplest solution should be to yield locks before calling &quot;waitForConditionOrInterrupt&quot;.&lt;/p&gt;</description>
