            <title>[SERVER-8762] Large one-time spike in DB write lock micros</title>
                <link>https://jira.mongodb.org/browse/SERVER-8762</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A DB-specific write lock saw a one-time ~213 day spike in micros between a 1 minute span. (37008987922471 -&amp;gt; 55455750947083)&lt;/p&gt;

&lt;p&gt;First observed in MMS as a 34m spike in lock %, but ultimately traced back to serverStatus changes between consecutive MMS agent pings.&lt;/p&gt;

&lt;p&gt;Believe this has been reported by other clients on MMS side; will update ticket if I find more instances of lock % spikes.&lt;/p&gt;</description>

&lt;p&gt;Given the lack of definitive details to reproduce/investigate this issue, I&apos;m going to close it.&lt;/p&gt;

&lt;p&gt;It&apos;s possible this is more of a reporting anomaly in MMS than a server issue; if you have any further context to add or suggestions on how to reproduce please comment.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
Stephen&lt;/p&gt;</comment>
