On some multiprocessor computers, programs with multiple threads thatuse the CreateProcess() or CreateProcessAsUser() API calls to start processes do not start because of desktop heap leaks. This inability to start results in a User32.dll or Kernel32.dll file initialization error when the desktop heap is exhausted.
This problem occurs because the thread object reference count breaks. The thread object reference count breaks because of a threadlockobjectinstruction within Win32k.sys that was not multiprocessor safe. Thiscauses programs to quit abnormally. Because of the abnormalway in which the program quits, the desktop heap leaked until new processes could not be started. In some other instances, when a program quits abnormally, a blue screen error message may be displayed.
