            <title>[SERVER-74244] Data race on namespace stored in RecordStore during rename</title>
                <link>https://jira.mongodb.org/browse/SERVER-74244</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Rename operations normally use copy-on-write as the concurrency control on Collection instances. However, there&apos;s a separate namespace variable stored in the RecordStore that is shared among all Collection instances.&lt;/p&gt;

&lt;p&gt;As reads do not take Collection locks we may read this variable concurrently with a new value being written even as the rename operation holds a MODE_X lock on the collection.&lt;/p&gt;</description>
