If the KeBugcheckEx() function runs on a multiprocessor Microsoft Windows Server 2003-based computer, the computer may experience a triple fault exception. This scenario forces a restart.
This problem occurs because machine check exceptions are delivered to multiple processors on the computer at the same time. When this problem occurs, the KeBugCheckEx() function may be running on a secondary processor while another processor is performing a task, such as a memory dump. The result is a triple fault exception that forces an automatic reset of the computer.
To resolve this problem, apply the hotfix that is described in Knowledge Base 835768.
