            <title>[SERVER-47543] Hedge reads request hang when hedge read finishes first with MaxTimeMSExpired error</title>
                <link>https://jira.mongodb.org/browse/SERVER-47543</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This is an intermittent failure that causes a read command to hang indefinitely when hedge reads are enabled and permitted i.e. as with &lt;tt&gt;readPreference&lt;/tt&gt; mode &lt;tt&gt;nearest&lt;/tt&gt; &lt;br/&gt;
The root cause is that if a hedge read that expired with MaxTimeMSExpired error before the original request will be ignored but as it triggers the finish line the follow-up response will be ignored as well.&lt;/p&gt;
