            <title>[SERVER-10189] Server crash under load</title>
                <link>https://jira.mongodb.org/browse/SERVER-10189</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Looks like a lack of memory. Either way I would expect it to slow down and not crash.&lt;/p&gt;

Under this kind of memory pressure, you&apos;re pretty likely to get killed by the kernel OOM-killer eventually, too.  To keep write latency low, MongoDB requires very large amounts of RAM for buffering disk operations.&lt;/p&gt;</comment>
