High non-paged pool with no stack specified

Question

So, I followed a guide https://superuser.com/a/988819/662442 to trace a non-paged leak of 4Gb of RAM. In vain. After loading symbolds, no stack is shown for my tag. I can't find any clue as to what to do next.

Answer 1

This means that the allocations were done outside of the trace. Do a rightclick on the columns in WPA and add the Type and move AIFO (allocated in trace but not freed inside the trace) to the front as you can see in my picture:

Those allocations will show a stack.
