> ParentQueue capacity cannot be set to 0 when child capacities > 0. To disable
> a parent queue temporarily, user can only STOP the queue but the capacity of
> the queue cannot be used for other queues. Allowing 0 capacity for parent
> queue will allow user to use the capacity for other queues and also to retain
> the child queue capacity values. (else user has to set all child queue
> capacities to 0)
