Invalid Page Fault

An invalid page fault is a type of page fault that produces an error. Page fault errors can occur for any of the following reasons:

  • The virtual memory system becomes unstable due to a shortage of physical memory (RAM).
  • The virtual memory system becomes unstable due to a shortage of free disk space.
  • The virtual memory area is corrupted by a misbehaving application.
  • An application attempts to access data that is being modified by another running application.
  • The first two causes are the most common. These conditions can also cause a general protection fault (GPF).

    An invalid page fault is also called a page fault error (PFE).
