With *kgdb* , obtain this:

I use ipfw with dummynet because can use dynamically rules for shaping.
With altq, need to put rule for every host, in order to share bandwith
equal to all host in lan. If i have hundredth of host, this can be painful.
This is why i use dummynet with ipfw.

Hi!
I try to implement some load balancing using pf. I use also ipfw for
traffic shaping.
Have you tried to use traffic shaping with ALTQ inside pf ? Perhaps
there is a negative side-effect when combining ipfw and pf this way.
In pf.conf, my rules are this:
nat on $ext_if1 from $lan_net to any -> ($ext_if1)
nat on $ext_if2 from $lan_net to any -> ($ext_if2)
pass in on $int_if route-to { ($ext_if1 $ext_gw1), ($ext_if2
$ext_gw2),
($ext_if2 $ext_gw2) } round-robin from $lan_net to any keep state
pass out on $ext_if1 route-to ($ext_if2 $ext_gw2) from $ext_if2 to any
pass out on $ext_if2 route-to ($ext_if1 $ext_gw1) from $ext_if1 to any
All work fine, but after some time , my system reboot. I found with
dmesg, this error:
savecore: reboot after panic: vm_fault: fault on nofault entry, addr:
e13d0000
Mar 3 21:29:47 server savecore: reboot after panic: vm_fault:
fault on
nofault entry, addr: e13d0000
savecore: writing core to vmcore.1
Have you tried to extract a gdb stack trace from the core file ? See
