&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;What could be the reason for the regular closing and opening of connections to other cluster nodes? &lt;/p&gt;

&lt;p&gt;Can you open a new SERVER ticket describing the behavior and impacts that you&apos;re seeing?&lt;/p&gt;

&lt;p&gt;We are facing the similar issue, connections are being dropped out.&#160;&lt;br/&gt;
 We are using two mongos, three config servers along with two shards with one replica. All inside docker container.&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;br/&gt;
&lt;b&gt;Performance Impact: -&lt;/b&gt;&#160;&lt;/p&gt;

&lt;p&gt;MongoDB becomes idle and unresponsive to application.&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Thank you.&lt;/p&gt;

&lt;p&gt;I found no performance issues.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The log lines indicate that the TaskExecutorPool is expiring after being idle for 5 minutes. We found it an unusual behavior that these connection pools are repeatedly and immediately reopening, then expiring again. I&apos;m passing this along for further investigation.&lt;/p&gt;

&lt;p&gt;Are you experiencing any performance impacts from these log lines?&lt;/p&gt;

&lt;p&gt;Best,&lt;br/&gt;

&lt;p&gt;Thank you providing the log files from the host &lt;tt&gt;core-storage0203&lt;/tt&gt;. It&apos;s unusual that both nodes are seeing similar behaviors. While we continue to investigate, can you also provide log files from &lt;tt&gt;core-storage0101.example.com&lt;/tt&gt; that correspond with &lt;tt&gt;core-storage0203.example.com&lt;/tt&gt;? This will help correlate some of the behavior that we&apos;re seeing.&lt;/p&gt;

&lt;p&gt;Best,&lt;br/&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Topology of the cluster:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;10 replicasets with 3 nodes on each&lt;/li&gt;
	&lt;li&gt;3 mongo config servers&lt;/li&gt;
	&lt;li&gt;3 mongos&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The ftdc and the log files uploaded from the same host core-storage0101.example.com.&lt;/p&gt;

&lt;p&gt;I&apos;ve attached ftdc and the log file for host &lt;tt&gt;core-storage0203.example.com:27017&lt;/tt&gt; (on a different date, because for 2021-06-03 there are no more files.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;Thank you for uploading the log files. Based on the content and frequency of the log messages, it looks like the hosts in the logs are being shut down every 5 minutes.&lt;br/&gt;

&lt;p&gt;Can you provide the following information to help with our investigation?&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;What is the topology of your cluster?&lt;/li&gt;
	&lt;li&gt;Is the ftdc and the log files coming from the same host core-storage0101.example.com&lt;/li&gt;
	&lt;li&gt;Attach ftdc and log files for host &lt;tt&gt;core-storage0203.example.com:27017&lt;/tt&gt;.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;I uploaded a log that contains messages &quot;Dropping all pooled connections&quot; (2021-06-03T03: 28: 07 - 2021-06-04T03: 42: 07).&#160;Please look at it.&lt;/p&gt;

&lt;p&gt;I apologize for being unclear earlier. The metrics you provided span the date range of 2021-06-03T00:03:55.001Z - 2021-06-04T06:23:54.002Z.&lt;/p&gt;

&lt;p&gt;Unfortunately the ftdc files you uploaded do not cover the scenario where cluster nodes are being opened and closed. Could you also upload the log lines that cover a more recent instance of this behavior (2021-06-03T00:03:55.001Z - 2021-06-04T06:23:54.002Z)?&lt;/p&gt;
