问题现象描述：
nginx在运行时出现一些异常问题，此时静态页面（html）可以打开，但是不能加载动态页面，一直处于等待状态，此时重新启动nginx后恢复正常，查看日志错误内容如下：

2010/07/26 09:59:52 [error] 12929#0: *304919 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.10.4, server: 123.test.cn, request: "GET /index.php?module=default&submod=user_setting&method=user_home_page HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "123.test.cn", referrer: "http://123.test.cn/index.php?method=left&parent_id=121&section_id=default&open_mainframe=1"

2010/07/26 10:03:44 [error] 12930#0: *311831 connect() failed (110: Connection timed out) while connecting to upstream, client: 192.168.10.4, server: 123.test.cn, request: "GET /index.php?method=left&parent_id=3&section_id=customer&open_mainframe=1 HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "123.test.cn", referrer: "http://123.test.cn/index.php?method=top&section_id=&main_url="

也查找了原因，很多朋友也遇到这样的问题，但是没有解决，说是nginx不稳定的原因，如果不稳定，那QQ、迅雷怎么还用呢？

请兄弟们指教，谢谢！
