            <title>[SERVER-81232] Skip RSTL lock acquisition in TimestampMonitor calls</title>
                <link>https://jira.mongodb.org/browse/SERVER-81232</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The TimestampMonitor currently drops idents after the oldest timestamp has advanced. To do so it acquires the global lock + the default hierarchy. This includes the RSTL.&lt;/p&gt;

&lt;p&gt;In some situations, the ident drop operation can take a while, blocking stepdown since it requires the RSTL in MODE_X.&lt;/p&gt;

&lt;p&gt;As the operation does not require the RSTL we should explore skipping its acquisition since it will unnecessarily be blocking stepdown.&lt;/p&gt;</description>
