Messages at boot: Line 91: Address list too long

[netmd1234]

Hi,

At system startup the message "Line 91: Address list too long" appears.
I think this is a message from the shaper ipfw.

I only use ipv4 but ipv6 is enabled in the firewall.
Firewall: Settings: Advanced: IPv6 Options / Allow IPv6

I use in shapper several rules with a lot of addresses.

How to check which line / rule causes this error?
