KeepAlive issue help

[frank]

Hi, everyone

We have one issue trouble which related to keepalive, can anybody help
me out or provide some clue, Thanks a lot.

Let me describe the issue briefly.

- Nginx version: 07.62
- Load balancing algorithm: Round-robin(default)
- upstream configuration
upstream me2day {
        max_connections 50;
 
        server testweb002.mtod:80; # 1.8.7
        server testweb047.mtod:80; # 1.8.7
 
        server testweb081.mtod:80;
        server testweb082.mtod:80;
 
        max_connections 50;
}
- Load balanorcing wks well if keepAlive is off,
  but if we set "keepalive on", Load balancing doesn't work.The order of
servers seems to affect the "load".
