Freebsd, ipfw sched - config type = QFQ get frozen


I have some freebsd soft-router

$uname -r


code for ipfw:

 pipe 50 config bw 70Mbit/s
 sched 50 config type QFQ
 queue 502 config sched 50 weight 1 mask dst-ip 0xffffffff
 queue 501 config sched 50 weight 9 mask dst-ip 0xffffffff

 add 01501 queue 502 ip from to out via vlan*
 add 01601 queue 501 ip from any to any out via ng*
  1. vlans over device em1

  2. ng created my mpd5

After rebooting i see the same each times, after 6-15 hours of work all traffic through vlan and ng frozen.

If i delete ipfw rules 1501 and 1601 , traffic start works immediately.

If i use WFQ2+ policy for scheduler all works ok.

So, its a QFQ bug? or some my fault in config?
