Cause

A page fault (Exception 14) occurs when the page being requested has not been successfully loaded into memory. There are both healthy and unhealthy page faults:

A healthy page fault results in the page being loaded from swapped memory to physical memory. The program is then allowed to proceed after the data has been properly loaded into physical memory.
An unhealthy page fault occurs when the page is not loaded in memory, and the operating system is unable to load the page from swapped to physical memory.

Resolution
