I managed to break myself because I'd been fiddling with flows 32 in some cases, and my version returns ENOTSUPP for that which sqm doesn't catch... and ohhh.... boy... htb with a 1000 packet fifo buffer fallback... SUCKS! :) As for profiling, once again I found myself distracted by the ecn debate. Fitting ecn 500 flows through a 100mbit bottleneck results in 1300 packets outstanding 26 flows that can't start (presumably due to ecn fall back), and without ecn, 450 packets outstanding 3 flows that can't start.
