Php xDebug在端口9000（nginx）上随机启动大量连接

我在xdebug中遇到了以下问题：

当我尝试连接到xDebug并通过从浏览器发送请求开始调试时，使用

？xDebug_SESSION_start=netbeans xDebug

，会有很多连接到端口9000，如

netstat-a | grep 9000

这似乎是随机发生的。如果幸运的话，netstat-a | grep9000只显示一个连接，一切正常。但当存在多个连接时，调试将无法工作。唯一的解决方案是停止调试器，并终止端口9000上的所有连接

问题是在不久前从Apache切换到Nginx时出现的

nginx版本：nginx/1.6.1 使用PHP5.5.15在Ubuntu服务器12.04.5 LTS上运行

我已经能够重现这个问题，因此，当我在Chrome中启动调试会话（使用扩展名'xDebug Helper'）比在netbeans中启动调试会话更早时，就会出现这个问题

因此，首先从netbeans启动调试会话，然后在chrome中启动调试会话，就解决了这个问题
