The following document describes how to obtain a .DMP file for a running application that is in an erroneous state for diagnostics.
Create .DMP File
Open taskmgr.exe (defaults to 64 bit if trying to debug turbo server service). The 32 bit taskmgr.exe can be found under c:\windows\syswow64 on 64 bit Windows.
For Turbo Server service, you can find the process by looking at the command line column by right clicking the task manager column. Look for Turbo Virtual Machine with command line TurboServer-Service.exe.
Right click on the process and select Create Dump File.
Alternatively, you can use WinDbg to create the file. A portal version can be found here.
To create a dump file using WinDbg, attach the process and run the command:
> .dump /ma c:\path\to\your\dump
Debugging Dump Files
To debug the .DMP file, open in windbg x64 using file open crash dump.
You can debug .NET applications by using the sos module:
> .loadby sos clr > !eestack -ee
If .loadby fails with some load module errors, make sure the bitness of windbg is correct. Detailed documentation can be found here.
To look at a stack on a specific thread, ex: thread #6
> ~6s > !dumpstack
