Bug Description
System has 3 config and 4 control nodes, auto load balancing enabled for ifmap, below is the behaviour seen in discovery:
Discovery clients ( dns, control in this case) keep on switching from one instance of publisher to other instance(ifmap in this case)
check IN USE count of the instances of publisher
Discovery server keeps on returning a new set of publishers( even though system seemed to be load balanced 2,3,3 in this case) i.e. Discovery failed to figure out a stable allocation for ifmap
