I'm also getting random crashes with a similar setup

I have these in my custom kernel
device         if_bridge
options        LIBALIAS
options        IPFIREWALL
options        IPFIREWALL_DEFAULT_TO_ACCEPT
options        IPFIREWALL_NAT
options        IPDIVERT
options        IPSTEALTH

My ipfw rules
00101 allow ip from any to any via lo0
00102 divert 8668 ip from any to me in via igb1
00103 divert 8668 ip4 from 10.100.0.0/23 to not me out via igb1
00104 deny ip from any to any 25 via igb0
00200 deny ip from any to 127.0.0.0/8
00300 deny ip from 127.0.0.0/8 to any
65535 allow ip from any to any

rc.conf
natd_enable="YES"
natd_flags="-f /etc/natd.conf"
natd_interface="igb1"
gateway_enable="YES"
firewall_enable="YES"
firewall_type="OPEN"

/etc/natd.conf
use_sockets yes
same_ports yes
dynamic yes

I don't have debug turned on but ever since upgrading from 12.2 to 13.0-STABLE,
it has been randomly crashing every few hours. The server is an NFS file server
and PXE server so it doesn't see much external traffic, only lots of internal
traffic.
