            <title>[SERVER-33934] Creating an unsharded collection can cause dist lock to time out</title>
                <link>https://jira.mongodb.org/browse/SERVER-33934</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;when enough threads try to do it on the same database at the same time.&lt;/p&gt;

&lt;p&gt;This is because all of them will try to grab the dist lock on the database. The dist lock algorithm doesn&apos;t have fair scheduling so it is possible for a single thread to be starved by other threads if there is enough contention on it.&lt;/p&gt;</description>
