            <title>[SERVER-56165] Updating config.shards can lose information</title>
                <link>https://jira.mongodb.org/browse/SERVER-56165</link>

                    <description>&lt;p&gt;The ShardingReplicaSetChangeListener writes to config.shards from multiple nodes without synchronization or version information: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c6c9c62b8abe5ca36ec65320c813eaf81735f02a/src/mongo/s/mongos_main.cpp#L547&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/c6c9c62b8abe5ca36ec65320c813eaf81735f02a/src/mongo/s/mongos_main.cpp#L547&lt;/a&gt;. This can result in newer updates being replaced by older information.&lt;/p&gt;</description>

The bug that I was originally thinking about was before the refactoring that Kevin had did a few months ago. When I sat down to look at the code to enter the details I realized that the Shard Registry was basically re-written. I&apos;ll reach out to you today on slack. This may not be a problem anymore.&lt;/p&gt;</comment>
