如何调试没有错误消息的错误？
当加载 PHP 页面时，我在 Firefox 中收到此错误。
The connection to the server was reset while the page was loading.
除了看起来是 Apache 崩溃之外，它没有给出任何其他原因。
Apache 错误日志显示：

我尝试搜索 3221225477 代码，但没有发现任何有效的结果。
Windows 事件查看器也显示了这一点：
Faulting application name: httpd.exe, version: 2.2.14.0, time stamp: 0x4aeb9704

当我打电话时会发生这种情况：
return mysql_fetch_object($result, $class_name);
当我使用时它也发生在另一个页面上$_SESSION
如果我改用 CGI 而不是php5ts.dll and php5apache2_2.dll I get:
Premature end of script headers: php-cgi.exe
它只发生在某些页面上。其他人工作正常。
- 没有发生 PHP 错误或异常。错误报告设置为
E_ALL & ~E_NOTICE & ~E_DEPRECATED. display_errors is on.
- 超时设置为60秒，大约10秒后返回错误页面。
- 内存使用量约为16MB，最大限制为256MB。
- PHP 5.3.1，Windows 7 64 位。
那么有谁知道如何有效地调试这个错误？
