The min_wire_version and max_wire_version attributes have always been racy when connected to a mixed version replica set or any sharded cluster. When connected to a mongos all you know is the wire version of that mongos, not the shards behind it. With mongos load balancing this problem is even worse, since each operation could possibly be executed on a different mongo version during an upgrade. |
