&lt;p&gt;We haven&#8217;t heard back from you for some time, so I&#8217;m going to mark this ticket as resolved. If this is still an issue for you, please provide additional information and we will reopen the ticket.&lt;/p&gt;

&lt;p&gt;We still need additional information to diagnose the problem. If this is still an issue for you, would you please see my previous comment?&lt;/p&gt;

To continue researching the possibility of a bug, we still need more information. If you still need help, can you:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Provide matching diagnostic data and log files for the Primary and Secondary. You can upload them to this &lt;a href=&quot;https://10gen-httpsupload.s3.amazonaws.com/upload_forms/2262167a-b439-40e3-b4ec-0179b6c844f1.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;secure upload portal&lt;/a&gt; where they will only be visible to MongoDB employees and will be deleted after some time.&lt;/li&gt;
	&lt;li&gt;Let us know if setting TCMALLOC_AGGRESSIVE_DECOMMIT did or did not help with this.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Thanks in advance.&lt;/p&gt;</comment>

Are the complete logs for the Secondary from 2019-05-27T08:21:44.586Z to 2019-05-27T10:31:48.053Z available? And if so could you provide them?&lt;/p&gt;</comment>
                            <comment id="2266420" author="adamof" created="Fri, 31 May 2019 12:19:20 +0000"  >&lt;p&gt;&lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/attachment/218632/218632_primary_diagnostic.data.tar&quot; title=&quot;primary_diagnostic.data.tar attached to SERVER-41326&quot;&gt;primary_diagnostic.data.tar&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://jira.mongodb.org/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;There you go &lt;img class=&quot;emoticon&quot; src=&quot;https://jira.mongodb.org/images/icons/emoticons/smile.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

It could be that memory simply wasn&apos;t being reclaimed swiftly enough at crash time.&lt;/p&gt;

&lt;p&gt;Setting a TCMALLOC_AGGRESSIVE_DECOMMIT environment variable to 1 on this node may be a workaround for you.&lt;/p&gt;

&lt;p&gt;Still, we&apos;re looking at this further to make sure something else isn&apos;t going on.&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://jira.mongodb.org/secure/attachment/218574/218574_Screen+Shot+2019-05-30+at+10.48.37+AM.png&quot; width=&quot;100%&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt; &lt;/p&gt;

&lt;p&gt;Again, data from the Primary may be of help.&lt;/p&gt;</comment>

&lt;p&gt;Because activity on the Primary node can provide important context for Secondary activity, it would be helpful if you could attach the diagnostic data for the Primary during these OOMs as well. Thanks in advance!&lt;/p&gt;</comment>

We haven&apos;t seen this issue on primaries, I&apos;m uploading the diagnostics data from the secondary.&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/attachment/218378/218378_diagnostic.data.tar&quot; title=&quot;diagnostic.data.tar attached to SERVER-41326&quot;&gt;diagnostic.data.tar&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://jira.mongodb.org/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;</comment>
                            <comment id="2264445" author="eric.sedor" created="Wed, 29 May 2019 21:21:00 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=adamof&quot; class=&quot;user-hover&quot; rel=&quot;adamof&quot;&gt;adamof&lt;/a&gt;, would you please archive (tar or zip) the &lt;tt&gt;$dbpath/diagnostic.data&lt;/tt&gt; directory (described &lt;a href=&quot;https://docs.mongodb.com/manual/administration/analyzing-mongodb-performance/#full-time-diagnostic-data-capture&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;) and attach it to this ticket? Can you please do this for both the Primary and the Secondary experiencing an issue?&lt;/p&gt;

&lt;p&gt;An initial possibility we&apos;ll be looking to confirm or rule out is if this is a case of&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-33296&quot; title=&quot;Excessive memory usage due to heap fragmentation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-33296&quot;&gt;SERVER-33296&lt;/a&gt;.&lt;/p&gt;</comment>
