+#### Serve Metrics with Multiple Listeners
+
+When there are multiple listeners configured for Addresses.API, serving metrics resulted in errors: "xxx was collected before with the same name and label values". This is now fixed by creating and reginstering metrics exporters and instruments once. These are used as handlers when serving metrics once, and now the same once-registered handlers are provided to the mux for every listener.
