10% of traffic to a rack was corrupt? Is that common? That seems really bad if 10% of all TCP traffic is dropped due to corruption.

It turns out that hardware can fail in weird ways. Its not common, but it appears that it is not uncommon that the memory in a network device can go bad. When this happens, lots of packets are corrupted. I have a description of how I think this happens: http://www.evanjones.ca/tcp-and-ethernet-checksums-fail.html
