            <title>[SERVER-7461] Possible for simultaneous aggressive chunk reload on many connections to prevent all shard versioning</title>
                <link>https://jira.mongodb.org/browse/SERVER-7461</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If you bring up many connections to a mongos at once this can cause a large amount of config reloads for the same data, causing the sequenceNumber to continually increase, preventing threads from successfully reloading config data.&lt;/p&gt;</description>
