What network card and driver are you using?
What happens to the server if you pull and reconnect the network
cable a few times under high network load. I would be interested
to see if the system panics and goes down in a few hours.

I don't think the negative number means much, there is a larger
request for buffer than a supply, so its an interpreted metric.

Whats it the original problem you are seeing?
