Hi,

which distro, kernel & nic are you using.

I saw this before with intel nic cards & the 2.4.20 kernel.

I suggest that you updgrade your kernel.

Thanks,
JP

This problem happens randomly for your kernel number.
The source is that your mtu (max packet size) is supposely 1500, and sometimes your kernel had a header that gets the size bigger (whereas it is not !).
2 solutions :
1. check latest driver for your card (on Red Hat, it's at http://hardware.redhat.com/hcl/
2. If you do not find your way there, update your kernel (do you know how to ? Depends on your distro too).
