            <title>[SERVER-14747] memory leak in the MultiPlanStage</title>
                <link>https://jira.mongodb.org/browse/SERVER-14747</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The MultiPlanStage deletes all pointers which it owns, except for the QuerySolution for the winning plan. The MultiPlanStage should either keep ownership of all QuerySolutions, or transfer ownership of the winning solution to the PlanExecutor.&lt;/p&gt;

&lt;p&gt;This issue affects 2.7 versions only, and does not affect any production releases.&lt;/p&gt;</description>
