            <title>[SERVER-24284] RangeDeleter hangs for 10+ hours</title>
                <link>https://jira.mongodb.org/browse/SERVER-24284</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;From the below log, it shows the RangeDeleter is blocked by the same cursor ids for 10+ hours. However from currentOp I can&apos;t find any long run operation. Is there any way to kill this cursors?&lt;/p&gt;

&lt;p&gt;Since this is expected behavior I&apos;m going to close this ticket. For MongoDB-related support discussion please post on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt; or &lt;a href=&quot;http://stackoverflow.com/questions/tagged/mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Stack Overflow with the &lt;tt&gt;mongodb&lt;/tt&gt; tag&lt;/a&gt;, where your question will reach a larger audience. A question like this involving more discussion would be best posted on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt;.
