> When the region is opened, we register the region to the ConfigurationManager as a ConfigurationObserver object.However, when the region is closed, we don't deregister the region as a ConfigurationObserver object from the ConfigurationManager correspondingly. It's not a bug for now cos we can update the conf  whenever the region is open or not.But it is bug-prone, and we should remove it from the ConfigureManager object when the region is closed.
