            <title>[SERVER-33385] MongoDB 3.6 crashes on Ubuntu 16.04 AWS when using Cold SC1 EBS Volume</title>
                <link>https://jira.mongodb.org/browse/SERVER-33385</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We&apos;re using the latest MongoDB 3.6 from the Ubuntu 16.04 x64 repositories, running Ubuntu 16.04 on t2.small instances, with 1TB SC1 EBS volumes used to store MongoDB.&lt;/p&gt;

&lt;p&gt;When trying to setup a sharded cluster, we&apos;re unable to reliably keep MongoDB instances running, and MongoDB frequently crashes with segmentation fault errors:&lt;/p&gt;

                            <customfieldvalue>&lt;p&gt;Spin up AWS t2.small Ubuntu 16.04 image with 1TB SC1 EBS volume. Install latest MongoDB from MongoDB repositories, format EBS volume to 1 XFS partition of 1TB. change MongoDB to use XFS partition for DB storage. Setup SSL and x509 certificates for mongo. Launch mongo.&lt;/p&gt;

&lt;p&gt;MongoDB shortly falls over.&lt;/p&gt;

&lt;p&gt;This predominantly seems to happen when a secondary connects to a master. The master then dies, and when restarted, the old secondary (now master), dies.&lt;/p&gt;</customfieldvalue>
