Hi All, 

I posted this a coupla days ago and just thought I would ask again in the
hope that someone had encounted something since then.

Has anyone here tried setting net.inet.ip.fastforwarding on in a high
traffic enviroment?

This setting DRASTICALLY speeds up transfers between boxes talking through
a freebsd gateway when you are using 2 100mbit interfaces, but it seems to
kernel panic the system after a few minutes.

Anyone got any ideas why its doing this, and any suggestions for fixing
it?

This problem was experienced under both 4.0-CURRENT and 4.0-STABLE

Thanks
