            <title>[SERVER-5909] renameCollection op is blocking, and killOp does not kill</title>
                <link>https://jira.mongodb.org/browse/SERVER-5909</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;During the execution of:&lt;br/&gt;
&amp;gt; db.runCommand( &lt;/p&gt;
{ renameCollection: &quot;mydb.oldname&quot;, to: &quot;mydb.newname&quot; }

&lt;p&gt;What happened:&lt;br/&gt;
Suddenly all the operations started to stack up. Collection in question was over 70GB. &lt;/p&gt;

&lt;p&gt;What was expected:&lt;br/&gt;
It was expected that the operation would yield. Or at the very least such behavior should be documented...&lt;/p&gt;

&lt;p&gt;Related:&lt;br/&gt;
db.killOp() - did NOT kill the operation&lt;br/&gt;
db.currentOP() - reported the OP as killed (killed:true), yet all the other ops never got executed. Additionally all the new ops continued to fill up the queue.&lt;/p&gt;

Its impossible to be yield as we rename an entire db.&lt;br/&gt;
SHould be doc&apos;ed though.&lt;/p&gt;</comment>
