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,

My Kernel 2.4.18-3
nic: Tigon3 - the build-in-card in a proliant dl 380

Thanks

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).
