--------------------------------------
Hello [~yzhangal] , ideally you are correct, numActiveConnections should be a
subset of numRegisteredConnections. So if you are seeing a different
observation, it may need to be investigated. Please let me know if you have any
more questions regarding this PR. Thank you.
