REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: ffffe28faac607d0, Object whose reference count is being lowered
Arg3: 0000000000000006, Reserved
Arg4: ffffffffffffffff, Reserved
   The reference count of an object is illegal for the current state of the object.
   Each time a driver uses a pointer to an object the driver calls a kernel routine
   to increment the reference count of the object. When the driver is done with the
   pointer the driver calls another kernel routine to decrement the reference count.
   Drivers must match calls to the increment and decrement routines. This BugCheck
   can occur because an object's reference count goes to zero while there are still
   open handles to the object, in which case the fourth parameter indicates the number
   of opened handles. It may also occur when the object's reference count drops below zero
   whether or not there are open handles to the object, and in that case the fourth parameter
   contains the actual value of the pointer references count.
