            <title>[DOCS-12935] Investigate changes in SERVER-41453: Raise the minimum file handle limit to trigger a startup warning</title>
                <link>https://jira.mongodb.org/browse/DOCS-12935</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;

&lt;h3&gt;&lt;a name=&quot;SERVERticketdescription%3A&quot;&gt;&lt;/a&gt;SERVER ticket description: &lt;/h3&gt;

&lt;p&gt;Currently, a startup warning is only triggered if the &lt;tt&gt;nofile&lt;/tt&gt; limit is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1041dd848e25e879260d1015d8da4f72ee7993fe/src/mongo/db/startup_warnings_mongod.cpp#L300&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;less than 1000&lt;/a&gt;.&#160;However, the production notes recommend a value of 64000.&lt;br/&gt;
Shouldn&apos;t the warning be triggered for a higher threshold, say 32000 to catch poorly optimized systems? There&apos;s probably many even at 1024 which get no warning.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;%C2%A0ChangeDescription%3A&quot;&gt;&lt;/a&gt;&#160;Change Description: &lt;/h3&gt;

&lt;p&gt;The minimum file handle limit that triggers a startup warning has been raised from 1000 to 64000. Most of our documentation recommends 64000 as a production value.&lt;/p&gt;

&lt;p&gt;I am not sure if any documentation about warnings exists or needs updated however.&lt;/p&gt;
