Hello, I haven't read the archive, but you probably talk about what I am thinking of. IIRC, at that time Carsten tried to explain how it works, but overall looked confused indeed. As a result, dispatcher module in 3.2.0 has a different system for gateway states. There are three of them: - active - inactive - disabled The active and inactive states can be set also in probing mode, so then there will be keepalives sent to gateways to detect when they become inactive/active. The disabled state is to put a gateway out of order completely. Maybe you can give a try to 3.2.0 dispatcher, now that it is out as a stable release, and see if it is more meaningful behavior.
