> This error can be reproduced by shutting down all servers in a rsgroups and starting them soon afterwards.
> The regions on this rsgroup will be reassigned, but there is no available servers of this rsgroup.
> They will be added to AM's pendingAssginQueue, which AM will clear regardless of the result of assigning in this case.
