            <title>[SERVER-32957] Remove notion of &quot;zombie cursors&quot; on mongos</title>
                <link>https://jira.mongodb.org/browse/SERVER-32957</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Now that we&apos;ve changed the ARM&apos;s &lt;tt&gt;kill()&lt;/tt&gt; to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-32307&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;not wait for outstanding batches&lt;/a&gt;, there should no longer be a need for &quot;zombie cursors&quot; or a &quot;zombie cursor reaper&quot; in &lt;tt&gt;mongos&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;Note that we&apos;ll need to preserve &quot;kill pending&quot; cursors, for the case when &lt;tt&gt;killCursors&lt;/tt&gt; is run an operation in the middle of a &lt;tt&gt;getMore&lt;/tt&gt;. The operation will be interrupted, and until the cursor is checked back in (or out), the it will be marked as &quot;kill pending.&quot;&lt;/p&gt;</description>
