            <title>[SERVER-55761] Once &quot;pthread_create failed&quot; error is detected, mongos should be shut down gracefully</title>
                <link>https://jira.mongodb.org/browse/SERVER-55761</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;While reproducing the production incident, it was determined and repeatedly reproduced that once mongos gets the first&#160;&quot;pthread_create failed&quot; error, it will not recover to the working state anymore. In some experiments, mongos was able to survive in this dysfunctional state for over 20 minutes.&lt;/p&gt;

&lt;p&gt;The proper behavior is to start graceful shutdown, drop active sessions, prevent new connections, exit when done or after 1 minute. Please remember that adding a shutdown thread is impossible, the termination procedure should complete in existing thread.&lt;/p&gt;

&lt;p&gt;I apologize for not knowing if the scope of this fix is not too much for one ticket, I would like to know more about our termination facilities in mongos.&lt;/p&gt;

&lt;p&gt;Mongod can be a separate ticket if needed.&lt;/p&gt;</description>
