Wow. That's pretty strange. I don't see any possibility for haproxy to do something like this, especially at the beginning of the data. But I can't imagine how nor why nginx would do that either. Also, it cannot come from the mongrel, otherwise haproxy would have returned a 502 error instead. However, I see that nginx replies "keep-alive". Would it be possible that the request was the second one in a row and that there is a problem somewhere with the previous response not been completely consumed by the client ? For this, it would help if you could try with another client then try to disable keep-alive on either your browser or nginx.
