Affect verions: at least 1.5.15 and 1.6.2
Here is the related part in my configuration:
timeout client 15m # 客户端响应超时
timeout client-fin 10s # 对客户端连接完成 TCP 4 次挥手超时
timeout connect 5s # HAProxy 向后端 Server 建立连接时的等候超时
timeout server 15m # 服务器端响应超时
timeout server-fin 5s # 对后端 Server 连接完成 TCP 4 次挥手超时
timeout http-keep-alive 5m # http keep-alive
连接空闲（等待下一请求到达）保持超时（对前后端均有效，影响 http-reuse 选项）
timeout http-request 15s # http 请求 *头部* 接收超时（对前后端均有效）
And I found after upgraded to 1.6.2 and 1.5.15, my haproxy server offen using
100% CPU. For example, here is the CPU usage graph of today:
I trace with pidstat (per 30 seconds) and haproxy debug level logging, And I
found this record in the log:
Nov 19 08:35:12 WD-G0-SRP1 haproxy[28267]: 58.246.225.90:24989
[19/Nov/2015:08:19:39.265] https-in~ g0n0/n0 724/0/0/1/933585 200 45430 - -
CD-- 13/12/2/2/0 0/0 "GET /lib/libbaiy/charcode.mapping/chs.json HTTP/1.1"
Nov 19 14:53:51 WD-G0-SRP1 haproxy[28267]: 46.4.123.172:20214
[19/Nov/2015:14:38:12.435] http-in WebSvr/ws0 0/0/1/2/939161 200 41488 - - CD--
52/21/0/0/0 0/0 "GET /app/wderp.apk HTTP/1.0"
These are the only two records show 15 minutes timeout today, and they are both
at the and of the cpu usage spike. I believe this is not a coincidence. May be
something is broken in the newest version of haproxy here?
