Hi Juha, this is the result of the different server design for UDP and TCP. For TCP AFAIK one main dispatcher accepts all the connections and then distribute them to the workers. For UDP the workers listen directly on the (one) network socket, so there is no dispatcher. It looks like a waste of resources, but its from a implementation POV much easier.
