I use HAProxy as LB for 3 backend web (Apache, same code).  
Sometime client on browser get ERROR connection timeout when connect to HAProxy.  
I have written a custom script CURL from laptop to my web and run it (1 request per second, during 8 hours)  
If my script CURL execute request GET to HAProxy node as LB, sometime my script logged error Timeout request (1-2 ERROR per 20-30 minute). When ERROR Timeout request happend, i see log haproxy process request and return status 200 to client, respone time ~ 0.5s, but client dont get haproxy response.

If my script CURL execute directly request GET to Apache Web Server, it work Like a charm.

This my haproxy config: [https://paste.cloud365.vn/?77901e48f1c63e75#SeXKZfbDYUpQxM/B38wZQqkULfHXXW+pKHMz4mSuFNs=](https://paste.cloud365.vn/?77901e48f1c63e75#SeXKZfbDYUpQxM/B38wZQqkULfHXXW+pKHMz4mSuFNs=)

Share the output of `haproxy -vv`,the actual haproxy log showing this request as well as the curl request output with `-vv` verbose output.
