            <title>[SERVER-39939] Avoid taking any lock manager locks in the killCursors code path</title>
                <link>https://jira.mongodb.org/browse/SERVER-39939</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In the killCursors code path we acquire a collection lock via&#160;AutoStatsTracker which could cause a deadlock (e.g., when there is a parallel DDL task queueing up on taking a Global X lock). Ideally, we&apos;d want to re-design the killCursors code path to avoid any lock manager locks. Once it is done, the test from&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-35567&quot; title=&quot;Concurrency simultaneous replication tests - unblacklist snapshot_read_kill_operations.js and remove snapshot_read_kill_op_only.js&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-35567&quot;&gt;&lt;del&gt;SERVER-35567&lt;/del&gt;&lt;/a&gt; can be re-enabled (note that the test will require some modifications to avoid getting stuck in the killSessions state, see comments to&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-35567&quot; title=&quot;Concurrency simultaneous replication tests - unblacklist snapshot_read_kill_operations.js and remove snapshot_read_kill_op_only.js&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-35567&quot;&gt;&lt;del&gt;SERVER-35567&lt;/del&gt;&lt;/a&gt; for details).&lt;/p&gt;</description>
