            <title>[SERVER-1592] MongoDB find() opt benchmark test assert out of memory error</title>
                <link>https://jira.mongodb.org/browse/SERVER-1592</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$cursor = $collection-&amp;gt;find($query,array(&quot;UID&quot;))-&amp;gt;limit($limit_size);	&lt;/p&gt;

&lt;p&gt;When Use LoadRunner Run PHP Code(up here),System Memory Add over to 2.5GB,latest to crash!!&lt;/p&gt;

&lt;p&gt;My Question: Why Query Opt use amount of Memory and not release?&lt;/p&gt;

&lt;p&gt;Here is Stack Trace&lt;br/&gt;
