 The sharding loadbalancer has the caveat of being limited in its scalability in its current implementation. It uses "horizontal" sharding, which means that the slots on each invoker are evenly divided to the loadbalancers. For example: In a system with 2 loadbalancers and invokers which have 16 slots each, each loadbalancer would get 8 slots on each invoker. In this specific case, a cluster of loadbalancers > 16 instances does not make sense, since each loadbalancer would only have a fraction of a slot above that. The code guards against that but it is strongly recommended not to deploy more sharding loadbalancers than there are slots on each invoker.
