                <link>https://jira.mongodb.org/browse/SERVER-50365</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When there are long-running transactions the server can get stuck with the cache full of dirty data because the thread that is responsible for aborting timed-out transactions may become stuck trying to evict data that is pinned in cache by the long-running transactions that it&apos;s tasked with aborting.&lt;/p&gt;</description>
