---------------------------------------
Hi [~pgandhi] , thanks for your work here. I thought numActiveConnections is a
subset of numRegisteredConnections thus the former should be smaller than the
latter, somehow we are observing the former is larger than the latter. Wonder
if my understanding is correct or if you had similar observation? thanks.
