            <title>[SERVER-43214] Consider decreasing distlock retry timeout</title>
                <link>https://jira.mongodb.org/browse/SERVER-43214</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If we have a thread that tries to newly acquire the distlock on an aggressively quick cadence (less than a second), it&apos;s possible that threads that have been waiting on the distlock can get crowded out by the new request. We should decrease the retry timeout, so that retrying threads can have a more equitable chance to acquire the distlock.&lt;/p&gt;

&lt;p&gt;This ticket may alternatively act as a placeholder for more preferable solutions to the linked BF.&lt;/p&gt;</description>

&lt;p&gt;Without doing work to allow writes to proceed, this work however isn&apos;t immediately valuable&lt;/p&gt;</comment>

&lt;p&gt;No&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Isitdatacorruptionordataloss%3F&quot;&gt;&lt;/a&gt;Is it data corruption or data loss?&lt;/h4&gt;
&lt;p&gt;No&lt;/p&gt;

&lt;p&gt;Very likely if we recommit the random balancer policy&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;DoesitcauseBuildBaronnuisanceandnoiseintheshardingtests%3F&quot;&gt;&lt;/a&gt;Does it cause Build Baron nuisance and noise in the sharding tests?&lt;/h4&gt;
&lt;p&gt;It will if we recommit the random balancer policy&lt;/p&gt;

&lt;p&gt;No&lt;/p&gt;

&lt;p&gt;4/4 &amp;#8211; might be an easy fix to implement, but could wide-reaching implications on the system as a whole.&lt;/p&gt;</comment>
