Description
The ShardingReplicaSetChangeListener writes to config.shards from multiple nodes without synchronization or version information: https://github.com/mongodb/mongo/blob/c6c9c62b8abe5ca36ec65320c813eaf81735f02a/src/mongo/s/mongos_main.cpp#L547. This can result in newer updates being replaced by older information.
