            <title>[SERVER-14753] backup query solution for cached plans is leaked in get_executor.cpp</title>
                <link>https://jira.mongodb.org/browse/SERVER-14753</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A memory leak was introduced in 2.7 versions as part of the refactor from the CachedPlanRunner to the CachedPlanStage. The code linked below calls QueryPlanner::planFromCache(), but fails to cleanup the backup query solution:&lt;/p&gt;
