This happened when I started the upgrade from 2.6.25.x to
2.6.26 of my ipsec gateways: it take me few days to do: so,
for a week I have both 2.6.25 and 2.6.26 running.

this huge packet come from an ipsec tunnel? If yes
linux 2.6.26 is sending this huge packets: this error
happened also on systems where there are only ipsec
tunnels to other linux boxes.
