This bug only affects recent versions of 2.7.x.&lt;/p&gt;

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-15714&quot; title=&quot;Invariant failure when running aggregation against non-existent namespace&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-15714&quot;&gt;&lt;del&gt;SERVER-15714&lt;/del&gt;&lt;/a&gt;: Use massert on invalid db/ns lock attempt&lt;/p&gt;

&lt;p&gt;This generally indicates a malformed command, so shouldn&apos;t shutdown server.&lt;br/&gt;
