Question

我正在尝试使用WinDBG来分析我们其中一台生产机器的崩溃转储。我的问题的根源似乎是我有一个不同于生产机器的.NET框架版本，只是我不知道如何解决问题。当我转！sym吵闹然后运行！dlk（来自SOSEX）我得到以下错误，因为它试图找到mscordacwks dll

我从生产机器上获取了mscorwks.dll，mscordawks.dll和sos.dll，并将它们放在C：\ mysymbols中。看起来WinDBG正在寻找mscorwks dll中的dll。

Answer 1

在这种情况下，这个非常完整的explanation by Doug Stewart帮助了我。

要点：

从原始系统获取mscordacwks.dll。
将其重命名为mscordacwks_AAA_AAA_2.0.50727.xxxx.dll（取决于您的体系结构和特定框架版本） - 例如mscordacwks_x86_x86_2.0.50727.3607.dll针对问题中的具体案例。
将该文件复制到windbg.exe。

Answer 2

在这2个命令之后，一切都变好了：

0:000> .symfix
0:000> .reload

Answer 3

在此处查看文章http://codenasarre.wordpress.com/2011/06/22/sending-an-sos/

之后

然后我基本上尝试了每一个移动符号的化身，我发现我能使这个工作的唯一方法是将mscorwks.dll，mscordawks.dll和sos.dll从生产机器复制到C： \ Windows \ Microsoft.NET \框架\ V2.0.50727

似乎WinDBG在同一DLL的多个版本中表现不佳。也许我做错了什么，但是直接将dll复制到.NET Framework目录至少让我开始运行。

Answer 4

我还发现使用64位版本的windbg并调试“Any CPU”托管代码项目，其中构建设置为“prefer 32 bit”将导致此错误。

Answer 5

除了CodeFox的答案之外，您还需要将mscorwks.dll（或者如果您使用.NET 4+的clr.dll）放在WinDbg中的图像文件路径中的目录（关闭）文件菜单）。

为什么WinDBG找不到mscordacwks.dll？
