.net - IIS 中 .NET 代码的堆栈溢出，但 Winforms 中没有

Question

所以我有一个令人讨厌的堆栈溢出，我在过去 8 小时左右一直试图追踪/解决，我正处于我认为我需要建议的地步。

细节：有趣的是，当在我们的常规 winforms 应用程序的上下文中调用时，这段代码运行良好——但我的任务是编写我们软件的基于 Web 的版本，当从在 IIS 上运行的 ASPX 页面。我做的第一件事是附加并尝试通过 Visual Studio 进行正常的 .NET 调试。在异常点，调用堆栈似乎相对较浅（我们的代码大约 11 帧深），我找不到堆栈溢出的常见嫌疑人（错误的递归、自调用构造函数、异常循环）。

所以我放弃了自己去打破windbg和SOS——我知道这对这类事情很有用，尽管我自己的经验有限。经过几个小时的闲逛，我想我有一些有用的数据，但我需要一些帮助来分析它。

首先是一个!dumpstack，我在堆栈溢出即将下降之前被破坏了。

^^ 我不得不剪掉上面的一些内容以使这篇文章适合，但想象一下它会继续这样下去^^

请忽略我们自定义代码的详细信息。这一切对我来说似乎都是多余的，但我不是堆栈专家。上面列出的大多数堆栈对象（有 1500 多个）不是函数参数，所以我认为它们不属于那里。这是在堆栈上生成所有这些项目的代码类型的示例（运行大量这样的代码）：

gUnitType.Questions("French Door Style").CommonLogicValue = CommonLogicValues.AlwaysDisplay
gUnitType.Questions("French Door Style").ShowAllAnswers()
If Me.NumberOfUnits > 1 Then
    Me.Dimensions("Call Size Height").Answers("6-8 Handicap sill").Visible = False
    Me.Dimensions("Call Size Height").Answers("6-10 Handicap Sill").Visible = False
    Me.Dimensions("Call Size Height").Answers("7-0 Handicap Sill").Visible = False
    Me.Dimensions("Call Size Height").Answers("8-0 Handicap Sill").Visible = False
End If

我也不是 VB 专家（这段代码来自我通常不使用的应用程序的不同部分），但是这样的代码用东西填满堆栈是否正常？如果有人有任何见解，或者甚至可以向我指出一些资源的方向以及有关此类东西的信息，将不胜感激。感谢您的关注！

我想我会在这里发布解决方案，以防其他人遇到它。上面的回复都很有帮助，并指出了为什么我可能会溢出堆栈——但我仍然无法理解的是为什么完全相同的代码在我们的 winforms 应用程序中运行良好。

我最终发现，微软在某个时候将 IIS 线程的堆栈大小从 1MB（如在一般 .NET 上下文中）更改为 256k。这解释了一切，包括一个特别令人沮丧的事实，即使 ASPX 版本在 Visual Studio 开发服务器下也能正常运行。我通过与这个特定客户合作解决了这个问题，以大幅减少上述 QuestionChangeLogic 函数中的代码量（当我查找源代码时，该函数有 > 15,000 行！）。

谢谢你们的帮助。

您需要一些适合 CLR 的符号。设置_NT_SYMBOL_PATH（在 WinDBG 中，使用文件/符号文件路径），使其包括：

SRV*C:\WebSymbols*http://msdl.microsoft.com/download/symbols

这告诉调试器符号引擎它可以将符号从 Microsoft 的在线符号服务器下载到 C:\WebSymbols。如果您希望将它们缓存在其他位置，请选择另一个文件夹。

看起来 Question、QuestionList、Answer 等都是structs - 即值类型 - 所以它们分配在堆栈上而不是堆上。您可能需要创建自己的class包装这些类型，以便它们位于堆上。

根据堆栈对象转储“ASI.ParadigmPlus.GrilleApp.GA1000”为 96872 字节。您可能想弄清楚该对象的全部内容。那是你堆栈空间的很大一部分。

分析调用堆栈我清楚地看到导致此异常的方法是：

ASI.ParadigmPlus.LoadedWindows.WID904.QuestionChangeLogic

这个方法怎么有315个变量？这不是太多了吗？

“！clrstack -a”（在运行“！dso”之后）应该为您提供每个托管帧的更多信息。

.net - IIS 中 .NET 代码的堆栈溢出，但 Winforms 中没有
