我昨天在这里发布了一个关于stackoverflow的问题，但认为这可能与服务器有关。 我使用PHPcurlfunction连接到一个服务器，然后生成一个PDF文件并将其发回，我只在第一次执行脚本时得到错误，再次执行时完全正常。 有关更多信息，请查看stackoverflow上的问题。
我收到这个消息
* About to connect() to 196.41.139.168 port 80 (#0) * Trying 196.xxx.. * connected * Connected to 196.xxx (196.xxx) port 80 (#0) > POST /serve/?r=pdf/generatePdf HTTP/1.1 Host: 196.xxx Accept: */* Content-Length: 7115 Content-Type: application/x-www-form-urlencoded Expect: 100-continue * Recv failure: Connection reset by peer * Closing connection #0 012 20:23:49 GMT < Server: Apache/2.2.15 (CentOS) < X-Powered-By: PHP/5.3.3 < Connection: close < Transfer-Encoding: chunked < Content-Type: text/html; charset=UTF-8 < * Closing connection #0 现在为什么我要求在serverfault上查询是否需要设置服务器上的一个设置，这是一个VPS运行CENTOS 6，使用WKHTML2PDF，安装了LAMP和CURL。 任何需要解决这个问题的信息，我都可以得到..我正在用尽想法。
