Kev*_*vin 41 asp.net stack-overflow debugging
问题
我有一个ASP.NET 4.0应用程序崩溃与一台计算机上的堆栈溢出,而不是另一台计算机.它在我的开发环境中运行良好.当我将站点移动到生产服务器时,它会抛出堆栈溢出异常(在事件日志中看到)并且w3wp.exe工作进程死亡并被另一个进程替换.
我到目前为止所尝试的内容
为了参考,我使用调试诊断工具来尝试确定导致溢出的代码片段,但我不确定如何解释它的输出.输出如下.
ASP.NET网站如何在一台计算机上导致堆栈溢出而在另一台计算机上导致堆栈溢出？
有经验的领导表示赞赏.我将把结果解决方案发布到导致我的答案之下.
调试输出
应用程序:w3wp.exe Framework版本:v4.0.30319描述:由于堆栈溢出,进程终止.

这个问题有点陈旧,但我刚刚找到了一个很好的方法来获取我的应用程序的堆栈跟踪之前溢出,我想与其他googlers分享:
当您的ASP.NET应用程序崩溃时,一组调试文件将转储到此主文件夹内的"崩溃文件夹"中:
C:\ ProgramData \微软\的Windows\WER\ReportQueue
可以使用WinDbg分析这些文件,您可以从以下链接之一下载:
在应用程序崩溃的同一台机器上安装后,单击文件>打开崩溃转储,然后在"崩溃文件夹"中选择最大的.tmp文件(我的文件大小为180 MB).就像是:
AppCrash_w3wp.exe_3d6ded0d29abf2144c567e08f6b23316ff3a7_cab_849897b9\WER688D.tmp
然后,在刚刚打开的命令窗口中运行以下命令:
.loadby sos clr
!clrstack
最后,生成的输出将在溢出之前包含您的应用程序堆栈跟踪,并且您可以轻松地跟踪导致溢出的原因.在我的情况下,这是一个错误的日志记录方法:

感谢Paul White和他的博客文章:Debugging Faulting Application w3wp.exe崩溃
w3wp.exe的默认堆栈限制是一个笑话.我总是提高它editbin /stack:9000000 w3wp.exe,它应该足够了.首先摆脱堆栈溢出,然后调试你想要的任何东西.
