The kernel i'm running here doesn't have any DTrace facility enabled (it is 
just the plain GENERIC kernel with ipfw, natd (divert) and kernel nat 
support).

But my system is running on zfs exactly like Florian reported, so it may be 
related.

This firewall is running fine (in production) all day long without any other 
problem.

Here is what i'm using on my rc.conf wich also may be relevant for debug:

hostname="fw-sp.xxxxxxx.com.br"
cloned_interfaces="vlan0 vlan1 vlan2"
ifconfig_bge1="up"
ifconfig_vlan0="vlandev bge1 vlan 100"
ifconfig_vlan1="vlandev bge1 vlan 101"
ifconfig_vlan2="vlandev bge1 vlan 102"

ipv4_addrs_bge0="90.0.1.1/24"        # internal address - don't ask...
ipv4_addrs_vlan0="xxx.x.x.x/28"       # external address - uplink 1
ipv4_addrs_vlan1="xxx.x.x.146-148/29"    # external address - uplink 2
ipv4_addrs_vlan2="192.168.2.1/24"    # dmz network - i've some nated address 
here
defaultrouter="x.x.x.x"    # uplink 1

And many thanks for the quick fix.
