            <title>[SERVER-4736] less aggressive resets on remote staleconfigexception</title>
                <link>https://jira.mongodb.org/browse/SERVER-4736</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When recving a StaleConfigException from a remote server, a less aggressive process would be as follows : &lt;/p&gt;

&lt;p&gt;1) If version required in exception matches the current cached version, we just need to reset the version on the connection itself.  This requires passing back the desired version as a field.  &lt;/p&gt;

&lt;p&gt;2) If version required != current version, we should reload the chunk manager if required.  Reloads should be explicitly rate-limited by a mutex, and on acquiring the mutex we should check to see if a newer version of the chunk manager now exists (or if the state has changed, i.e. the collection is now removed).&lt;/p&gt;

&lt;p&gt;3) Full reloads of the database should also be explicitly rate-limited, to avoid forcing all connections to re-establish their state.&lt;/p&gt;

&lt;p&gt;Potentially also reworking the sequence number logic to store versions-per-ns-per-shard-per-connection would also significantly reduce unnecessary round-trips to the shards.  &lt;/p&gt;</description>
