            <title>[SERVER-15632] MultiHostQueryOp::PendingQueryContext::doBlockingQuery can leak a cursor object</title>
                <link>https://jira.mongodb.org/browse/SERVER-15632</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In MultiHostQueryOp::PendingQueryContext::doBlockingQuery , the result of calling doBlockingQuery is only noted, causing an ownership transfer, if the parent op still exists.&lt;/p&gt;

&lt;p&gt;In the case where the parentOp no longer exists after doBlockingQuery, the DBClientCursor object is not freed.&lt;/p&gt;</description>
