0:001> !analyze -v
Invalid handle exception for current stack trace.
This stop is generated if the function on the top of the stack passed an
invalid handle to system routines. Usually a simple kb command will reveal
what is the value of the handle passed (must be one of the parameters -
usually the first one). If the value is null then this is clearly wrong.
If the value looks ok you need to use !htrace debugger extension to get a
history of operations pertaining to this handle value. In most cases it
must be that the handle value is used after being closed.
