我在我的NGINX error.log上发现了这个错误：
2011/05/09 23:33:52 [error] 22145#0: *1158 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: xx.xx.xxx.xxx, server: *.mywebsite.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9002", host: "mywebsite.com" 这是什么意思？ 可能是一个PHP的FPM问题？
