PHP On EC2挂起

Question

新的WinDBG调用堆栈。似乎与MySQL有关。

--- --- UPDATE

在Windows Server 2012上，在Amazon EC2上使用Java 7和PHP 5.3.29我运行了一个Java程序，它启动了我非常简单的PHP脚本（无法显示，因为它依赖于多个依赖项 - 很多代码）。如果出现问题，PHP脚本只会从mysql中获取内容并通过电子邮件发送给我。

此PHP脚本不会退出！ 我调用exit（）;在PHP文件的末尾。将此作为子进程启动的Java代码将错误流重定向到输入流，因此不会发生臭名昭着的缓冲区死锁。 Procmon不显示任何PHP.exe活动。

最后一张照片是我最关心的照片，我的剧本持续约10秒，不到1秒！
