Argh, kris beat me to mentioning the statistics problem.

Well, I'd add another potentially useful piece of data:

I don't think large socket buffers have been tested well, it's possible 
that you're exhausting almost all of your mbufs with just a few 
connections - if you're really stuffing that much data in.  I'd go back to 
the default settings for the above and try again.
