我一直困惑于此。在我们的一个客户端（Windows 7，.NET 2.0）计算机上，以下代码似乎失败（导致应用程序关闭）但似乎没有抛出异常。
在日志中打印“发送休息请求”，然后打印。我的期望是打印以下日志消息之一（其中一个例外或一个信息消息）。
浏览事件日志会显示Windows错误报告服务，然后在此时停止，但没有创建转储文件。
对于可能发生的事情或如何获取更多信息进行调试的任何见解将不胜感激。感谢

编辑：我应该添加这是一个瞬态错误（它每隔几天失败一次，只在这台机器上失败）。代码在200多台机器上运行
EDIT2：我还使用以下内容启动代码以捕获未经编辑的异常：
// Add the event handler for handling non-UI thread exceptions to the event.
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
// Add the event handler for handling UI thread exceptions to the event.
Application.ThreadException += Application_ThreadException;
// Set the unhandled exception mode to force all Windows Forms errors to go through
// our handler.
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
EDIT3：记录。记录代码肯定可能是导致崩溃的原因。我正在使用来自apache的Log4Net，它非常稳定，还有一个RollingFileAppender，它默认在每个日志请求后刷新。当日志级别不会记录警告时，也会发生错误。
EDIT4：运行procdump后，我能够在程序崩溃时捕获程序的转储。在Windbg中打开并运行！analyze -v

这句话很奇怪：
ERROR_CODE: (NTSTATUS) 0x80000003 - {EXCEPTION} Breakpoint A breakpoint has been reached.
记录器的代码中有一些Debbugger.Break或一些Debug.Assert？
