I tried the latest build which shows the same behaviour. Your hint about the keep-alive period seems to point into the right direction. Using a keep-alive period of around 35 seconds packets are sent correctly. But if i use smaller periods, packets are sent much too fast (30 seconds lead to a real period of 20 seconds, 18 seconds to 3 seconds and 15 seconds or lower to an immediate resent of the options packet). I checked this against 1.12.10 release again, where small keep-alive periods work perfectly. Although I agree that 15 seconds are very fast, I would like to fix this problem. Do you have any pointer into the code? Best Regards, Timo ___________________________________________________________ Schon gehört?
