I am debugging a service hang issue where critical section is being used as synchronization object between threads. I have taken the service memory dump file after it hangs.
When I run the !locks command in the dump file, it lists one CS having Lock count 7 as shown below. When I want to see the stack of the thread that is holding the CS, I see only one function in the stack and that thread is also waiting for an object. How can get full call stack of this thread to check what it is waiting for?
