      Description

      Mongos can crash if an error occurs with a replica set while trying to set the shard version - because checkShardVersion uses the legacy masterConn() call, it retains a pointer to the now-invalid connection.

      Potential fix is to retry not with the same connection but with the replica set connection object.
