&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-2252&quot; title=&quot;Coverity analysis defect 101971: Resource leak&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-2252&quot;&gt;&lt;del&gt;CDRIVER-2252&lt;/del&gt;&lt;/a&gt; leak in mongoc_client_kill_cursors&lt;/p&gt;

&lt;p&gt;Very minor leak: the topology must include incompatible servers, so no&lt;br/&gt;
operations will succeed in any case, and the application must call the&lt;br/&gt;
deprecated and useless mongoc_client_kill_cursors function repeatedly.&lt;br/&gt;
