Have you set "option httpclose" ? Otherwise, those would be keep-alive sessions. But judging from the very low rate, I doubt it.
It is also possible that some clients send pipelined requests and that nginx accepts them despite the "Connection: close" header. I must say that this case would be a bit strange because the clients should not send pipelined requests to non-keepalive servers, but that might be a reason for this.
