It has been my experience that this would be a PCI issue as interrupts occur for the PCI bus that the card is on. It may help to look at your motherboard docs and see if you have more that one PCI bus and make sure the eth card is on a bus by its self. This could also be overloading the CPU but not likely.

I would be happy to look at the dump for you. use some thing like this, when it happens. tcpdump -nn -i eth0 dst net <your IP> -- Chief Security Engineer | Daniel Fairchild [EMAIL PROTECTED] GCS d- s++:++ a- C++ UL++++ P+++ L+++ E--- W++ N++ o+ K- w+ O M- V PS+ PE Y+ PGP+ t 5+ X-- R+ tv b++ DI++ D
