Previous frame inner to this frame (corrupt stack?)
In ipfw I use tables, that then added to pipe, that configured with mask 0x=
ffffffff.
I have similar server with load much smaller under FreeBSD 7.0-RC3, but wit=
h similar configuration (used ipfw+tables+pipes, pf, mpd5), but in mpd I do=
n't using ng_car. May be using ng_car and dummynet together is corrupt?
