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? -- Best Regards BaiYang baiy...@gmail.com http://baiy.cn **** < END OF EMAIL > ****
