                            <comment id="989356" author="rujun" created="Mon, 27 Jul 2015 09:02:44 +0000"  >&lt;p&gt;I also encountered the same problem in 3.0.4&lt;br/&gt;
Under heavy load, two secondary of a 3 member replicaset went down One after another&lt;br/&gt;
the log is the same as this issue&lt;/p&gt;</comment>
                            <comment id="972597" author="schwerin" created="Wed, 22 Jul 2015 17:42:46 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=scotthernandez&quot; class=&quot;user-hover&quot; rel=&quot;scotthernandez&quot;&gt;scotthernandez&lt;/a&gt;, can you confirm that this is a dupe of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-17689&quot; title=&quot;Fatal assertion during replication, and/or initial sync&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-17689&quot;&gt;&lt;del&gt;SERVER-17689&lt;/del&gt;&lt;/a&gt; and close the ticket, if so?&lt;/p&gt;</comment>
                            <comment id="972051" author="wrichard" created="Wed, 22 Jul 2015 12:42:54 +0000"  >&lt;p&gt;I would guess that the backport in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-17689&quot; title=&quot;Fatal assertion during replication, and/or initial sync&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-17689&quot;&gt;&lt;del&gt;SERVER-17689&lt;/del&gt;&lt;/a&gt; addresses the issue&lt;/p&gt;</comment>
