Hi Ranga, There's not a lot I can deduce from your description below - what sort of problems are you having exactly using SUBS/NOT?
>From what i can gather, your setup includes a state agent at each member of the >"multicast" group. Have you considered a different model that has a dedicated state >agent for which the members PUBLISH their state, and who then takes care of >distributing that state?
