            <title>[SERVER-24085] LockManager doesn&apos;t grant all read requests on GlobalLock MODE_S grant</title>
                <link>https://jira.mongodb.org/browse/SERVER-24085</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When granting the global lock in MODE_S, the locking policy switches to compatibleFirst, allowing readers to skip queued writers. However, existing readers that are waiting behind writers on the global lock are not released.&lt;/p&gt;

&lt;p&gt;This may result in existing readers becoming blocked when running the fsyncLock command.&lt;/p&gt;</description>
