            <title>[SERVER-56995] MongoDB consumes up-to 90% of the memory in allotted for the replicas</title>
                <link>https://jira.mongodb.org/browse/SERVER-56995</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hello,&lt;/p&gt;

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

&lt;p&gt;I have configured mongodb with 3 replicas with 10G of memory each replica.&lt;/p&gt;

&lt;p&gt;The current wiredtiger cache is with the default which comes around 4G&lt;/p&gt;

&lt;p&gt;Found the primary pod consumes up to 98% of the memory during multiple connections and read requests . But it never releases the memory.&lt;/p&gt;

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

&lt;p&gt;Is there a way we can free the memory with some tuning.&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;root@cp0766node02 cloud-user&amp;#93;&lt;/span&gt;# kubectl top pod -n test | grep cmgo&lt;br/&gt;
e-cmgo-replica-0 92m 9433Mi&lt;br/&gt;
e-cmgo-replica-1 89m 6065Mi&lt;br/&gt;
e-cmgo-replica-2 96m 6482Mi&lt;/p&gt;

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

&lt;p&gt;Pod configuration&lt;/p&gt;

&lt;p&gt;Limits:&lt;br/&gt;
 cpu: 5&lt;br/&gt;
 memory: 10Gi&lt;br/&gt;
 Requests:&lt;br/&gt;
 cpu: 1&lt;br/&gt;
 memory: 2Gi&lt;/p&gt;

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

&lt;p&gt;&#160;&lt;/p&gt;</description>
