            <title>[SERVER-82872] Data race between setParameter and reads of gEnableDetailedConnectionHealthMetricLogLines</title>
                <link>https://jira.mongodb.org/browse/SERVER-82872</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The server parameter gEnableDetailedConnectionHealthMetricLogLines is accessed throughout the codebase in unsynchronized ways, but it can be written to at any time by a setParameter command. We should ensure that all accesses of this parameter are synchronized to avoid data races.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-82872&quot; title=&quot;Data race between setParameter and reads of gEnableDetailedConnectionHealthMetricLogLines&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-82872&quot;&gt;&lt;del&gt;SERVER-82872&lt;/del&gt;&lt;/a&gt; Use AtomicWord for gEnableDetailedConnectionHealthMetricLogLines&lt;/p&gt;

&lt;p&gt;This fixes a data race between the setParameter command and other reads of&lt;br/&gt;
gEnableDetailedConnectionHealthMetricLogLines, which are currently unsynchronized.&lt;/p&gt;

&lt;p&gt;Fixes BF-30638.&lt;br/&gt;
