            <title>[SERVER-4498] Creating a ShardConnection calls checkShardVersion on every shard</title>
                <link>https://jira.mongodb.org/browse/SERVER-4498</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Whenever a new ShardConnection is created, checkShardVersion is called on every single shard.  If you have many shards, and/or multiple shards are in mid-failover at that time, your mongos can wind up spending a ton of time making failing setShardVersion calls, rendering the mongos useless until it is restarted.&lt;/p&gt;</description>
