Description - Invalid handle exception for current stack trace

Verifier stop code 0300.

Call Stack � current call stack of last operation when handle was found to be invalid.

Frequency of this error is high.

To debug:
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.
