Hi!
I try to implement some load balancing using pf. I use also ipfw for 
traffic shaping.
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
Currently i use pf+ipfw, without load balancing, with pf doing only nat 
and some port redirection. That combination work without any problem.

My system is Freebsd 7 Release, on AMD 64x2 at 4200Mhz. I have installed 
i386 version, not amd version.
