Usage count = 1 We are using "tc" to do traffic shaping with the tbf (tocket bucket filter). Kernel is 2.6.9. I found the following which appears to be similar: http://marc.theaimsgroup.com/?l=linux-kernel&m=109317866203856&w=2 Except that it relates to cbq specifically. Could there be an issue with the tbf code as well? Ray
