> When calling {{dfsadmin -refreshCallQueue}} to update CallQueue instance, 
> {{maxQueueSize}} should also be updated.
> In case of changing CallQueue instance to FairCallQueue, the length of each 
> queue in FairCallQueue would be 1/priorityLevels of original length of 
> DefaultCallQueue. So it would be helpful for us to set the length of 
> callqueue to a proper value.
