Can anyone help explain this call stack? We have written a managed code DDL
that runs as an add-in for a third-party (unmanaged) server product. Things
usually work well, but occasionally we get some hung threads that all show
this call stack. None of out code is on the stack, but mscorwks is. What
is going on here?

Hi Stephen,

Thanks for your post.

Do you setup the symbols correctly for the debugger? From the call stack,
it seems that some symbols are not shown out.

Also, I do not think the pure call stack without user written code is
helpful to troubleshooting out the root cause regarding your problem. You'd
better explain your main work in corresponding technology groups to check
if you are doing the correct thing. Thanks

Best regards,

Your symbols aren't lining up, so this stack useful. It also looks
like you might have some managed executing in here which is not going
to show up when using kp.
