Hi, After having configured traffic shaping with Vuurmuur, I'm receiving the following messages on the console :
Jul 6 10:05:44 roberto kernel: HTB: quantum of class 20001 is big. Consi der r2q change. Jul 6 10:05:44 roberto kernel: HTB: quantum of class 30005 is small. Con sider r2q change. Jul 6 10:05:44 roberto kernel: HTB: quantum of class 30006 is small. Con sider r2q change. Should I worry ?

I reserved 132kbps for this stream. The uplink speed was specified on eth0 (8Mbps/384kbps). Thanks for your help ! Matthieu
