Less than half! Could there be something in userppp that I'm not settting up right?=20 Has anyone ever experienced this? I'm running isdnd in fullscreen debug mode so I can confirm that both ISD= N=20 channels are being used in the connection. Also, the arca technologies IS= DN=20 emulator that I'm using indicates that both channels are being used. With one channel I get transfer rates of around 7 kbps but with bundled=20 channels the transfer rates hover around the 2.5 kbps mark. Any help would be much appreciated.

The kernel is trying to allocate an mbuf for the D-Channel. Without it nothing can go forward. Since this is a situation which should never occur the I4B code treats this as a panic condition everywhere. Changing this behavior would entail a lot of work and probably would not result in good results anyway. --- Gary Jennejohn / garyj@jennejohn.org gj@freebsd.org gj@denx.de
