I'm not surprized, I remember about tux on 2.4 sometimes leaving frozen connections behind it when pushed to extreme speeds back in the days where it was audacious to pull 2 Gbps out of a Pentium3. I like it when we find very old issues when improving the code, it generally means we're stressing it a bit more and making more efficient use of it. Cheers, Willy
