            <title>[SERVER-67695] Remove the write-blocking mode of dbCheck </title>
                <link>https://jira.mongodb.org/browse/SERVER-67695</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The point-in-time snapshot mode of dbCheck (the default) seems to have been working well. Given that the default history window is 5 minutes, there is less of a risk of secondaries not having enough history to support a timestamped read in the past. This was more of a concern in 4.4 where the window was 5 seconds.&lt;/p&gt;

&lt;p&gt;We should remove support for the version that uses MODE_S locks and blocks writes, since it does not appear to be in active use.&lt;/p&gt;</description>
