Hi,

I am using FreeBSD 8.3 - RELEASE with ipfw + dummynet + inkernel_nat
compiled kernel.

This message appears on my console about 20 times per hour :

ipfw: opcode 10 size 49 wrong"
ipfw: opcode 10 size 49 wrong"
ipfw: opcode 10 size 49 wrong"
ipfw: opcode 10 size 49 wrong"
ipfw: opcode 10 size 49 wrong"
...


System works as expectedly but, it hangs after about 2-3 hours.

Both IPv4 and IPv6 addresses configured,
System has 3 interfaces ( 1 LAN, 1 WAN, 1 DMZ )
All of cards are Intel I350T ( igbX ).
kern.ipc.nmbclusters is set to 262144.

What does it mean "ipfw: opcode 10 size 49 wrong" ?
How can we debug / solve this problem?

Best regards,
Ozkan.
