            <title>[SERVER-42281] IndexBuildsCoordinator fails to clean up index build when lock acquisition times out</title>
                <link>https://jira.mongodb.org/browse/SERVER-42281</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If the &lt;tt&gt;IndexBuildsCoordinator&lt;/tt&gt; fails to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/888f3013fa3fe2dafb248e3996b4667c8075bda3/src/mongo/db/index_builds_coordinator.cpp#L749-L754&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;acquire the locks&lt;/a&gt; for the index build, it may leave the index build, with its corresponding &lt;tt&gt;BackgroundOperation&lt;/tt&gt;, in an unfinished state. This can happen when the &lt;tt&gt;createIndexes&lt;/tt&gt; is invoked with a short &lt;b&gt;maxTimeMS&lt;/b&gt; duration.&lt;/p&gt;

&lt;p&gt;The resulting inconsistent may affect subsequent metadata operations such as collections drops and renames that check &lt;tt&gt;BackgroundOperation::assertNoBgOpInProgForNs()&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;This is applies only when the IndexBuildsCoordinator is enabled for the createIndexes command.&lt;/p&gt;</description>
