w3wp.exe的崩溃 - ThreadAbortException

Question

我们有我们无法重现的问题，它随机发生运行ASP.NET 4

我们的Web服务器（Windows Server 2008数据中心64位，托管在亚马逊EC2）上

它在错误日志中ASP.NET警告（用一个很长的URL一个奇怪的GET请求）开始：

Exception information:
Exception type: HttpException
Exception message: The length of the URL for this request exceeds the configured maxUrlLength value.
at System.Web.HttpRequest.ValidateInputIfRequiredByConfig()
at System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext context)

然后一个错误：

Application ID: /LM/W3SVC/2/ROOT
Process ID: 4604
Exception: System.Threading.ThreadAbortException
Message: Thread was being aborted.
StackTrace: at System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context)
at System.Web.Hosting.PipelineRuntime.ProcessRequestNotificationHelper(IntPtr managedHttpContext, IntPtr nativeRequestContext, IntPtr moduleData, Int32 flags)
at System.Web.Hosting.PipelineRuntime.ProcessRequestNotification(IntPtr managedHttpContext, IntPtr nativeRequestContext, IntPtr moduleData, Int32 flags)

然后另一个错误：

Application ID: DefaultDomain
Process ID: 4604
Exception: System.Threading.ThreadAbortException
Message: Thread was being aborted.
StackTrace:

然后应用程序错误：

Faulting application w3wp.exe, version 7.0.6002.18005, time stamp 0x49e03238, faulting module kernel32.dll, version 6.0.6002.18005, time stamp 0x49e041d1, exception code 0xe0434352, fault offset 0x00000000000176fd, process id 0x%9, application start time 0x%10.

WinDBG的

我得到了一个转储与ADPlus的崩溃，但我真的不知道该找什么。我之前用Windbg解决了一些堆栈溢出问题，但我不知道使用哪种方法来处理这个错误。

线程与错误的PE：！

任何人有一个线索可能是什么？或者可以点我正确的方向来分析Windbg？

Answer 1

您应至少加载符号，然后查看调用堆栈中显示的正确字符串。

如果您无法处理此类分析，我认为通过http://support.microsoft.com打开支持案例对您有好处。

Answer 2

我一直在努力解决类似的问题。

我发现这篇文章声称这一个程序，以确定原因，我认为它实际上是有道理的：
