Hello, just to close this one: Server notification works fine, as long as you don't touch the first parameter of the callback function (message). I have it working within a greater context for some time now. To avoid the loop I just process the entries passed to the callback function, not the message. I didn't find the time to track down the real reason, but I guess this is not a big issue. If I get a clue about it, I will let you know.
Cheers, Dirk
