The TCP offloading should be suspect. Any current PC hardware should
be able to deal with huge amounts of traffic without any offloading.
Start with turning that off, so everything will be handled by Linux
directly. Even if you still would have a problem, it's easier to trouble
shoot without magic black boxes (TOE) in between.
