Question

我有ASP.NET应用程序。周期性地它会失败，让我的用户不高兴。

在日志中我看到：

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2

在崩溃转储中，我看到：

这是正常的应用工作。但在那之后呢？

但我不会遇到什么麻烦。

请告诉我如何解决这个问题。

看起来类似：http://connect.microsoft.com/VisualStudio/feedback/details/665157/nlssorting-fault-crashes-iis

您也可以在尝试使用类似代码捕获Global.asax.cs的Application_Error（）方法中的错误时找到价值：

protected void Application_Error(Object sender, EventArgs e) {
    Exception ex = HttpContext.Current.Server.GetLastError();
    // handle it
    HttpContext.Current.Context.ClearError();
}

随着时间的推移，你也可能会进入像How to get ELMAH to work with ASP.NET MVC [HandleError] attribute?

根据Microsoft的文档w3wp.exe遇到未处理的异常时会崩溃。

根据我的经验w3wp.exe崩溃，当堆栈由于溢出而无可救药地损坏时，由于内存损坏，try-catch块无法处理这种错误。

主要原因可能是递归调用过多，因为每次调用都会使用一定量的堆栈直到退出。可能有无限递归？

第二个原因是w3wp.exe或.NET Framework中的内存管理不佳，导致内存损坏而不是检测到这种情况并通知用户Stack Overflow。
