You should set srvtimeout and clitimeout to identical values in order to reduce corner cases, especially in TCP mode.

"stats enable" cannot work in TCP mode. I still wonder how this passed through without any warning!

Have you noticed that the status changes almost exactly every 10 minutes ? This regularity is quite troublesome.

It's abnormal, you have HTTP logs here while in TCP mode. What version of haproxy are you running ? This is what I consider a bug, but I'd like to know a bit more about the context. Also, would you happen to have any "defaults" section before your "listen" section ?
