            <title>[SERVER-29310] server crash during chunk split</title>
                <link>https://jira.mongodb.org/browse/SERVER-29310</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;4 days ago we upgrade from 3.0.7 to 3.2.13. We didn&apos;t have any crashes in a year but had 2 crashes on 2 different clusters since the upgrade. The first crash did not produce a stack trace but the second one did (please see attached log file). Here&apos;s the log from right before the crash and the stacktrace. It seems that the segmentation fault happened during a chunk split attempt.&lt;/p&gt;

&lt;p&gt;Thank you for these stack traces, they helped us track down the root cause of this issue, which is an internal race condition between the shutdown of different objects while threads within the server are exiting.  I&apos;ve written a bit more about this in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-29152&quot; title=&quot;Segfault in multiple shard primaries under regular load&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-29152&quot;&gt;&lt;del&gt;SERVER-29152&lt;/del&gt;&lt;/a&gt;, and we&apos;re going to use that ticket to track this bug and the status of a patch to fix it.&lt;/p&gt;

&lt;p&gt;Thank you,&lt;br/&gt;
Samantha&lt;/p&gt;</comment>
