Why isn't !locks working for me?
- by jeffamaphone
I'm using windbg (the latest available from the MSDN download page).
I'm trying to debug a deadlock in my app, and !locks would be very useful. However, it's not working:
0:023> !locks NTSDEXTS: Unable to resolve ntdll!RTL_CRITICAL_SECTION_DEBUG type
NTSDEXTS: Please check your symbols
I don't know why it's upset. I've got symbols properly loaded:
0:023> .sympath
Symbol search path is: srv*
Expanded Symbol search path is: cache*c:\debuggers\sym;SRV*http://msdl.microsoft.com/download/symbols
And NTSD agrees:
0:023> lmv m ntdll
start end module name
777b0000 77930000 ntdll (pdb symbols) c:\debuggers\sym\wntdll.pdb\E9D10FA3EB884A23A5854E04FB7E2F0C2\wntdll.pdb

And the stack looks good:

Any help is appreciated.
