Invalid page fault - A program uses memory (RAM) to store data. For example, when you load a document into Microsoft Word, large parts of the file you are editing take up space in RAM. As the program needs memory, it requests blocks of memory of specific sizes from the operating system. The program remembers the location of each block it allocates using a "pointer." If the program tries to write data to a location beyond the end of a memory block, or if the program gets confused and tries to access a non-existent block of memory using an invalid pointer, the operating system can see that happening and generates a "page fault" or a "segmentation fault." The operating system shuts down the program because the program obviously does not know what it is doing.
"the program gets confused"
"The operating system shuts down the program because the program obviously does not know what it is doing."
Made me laugh!

PS current status of my Solidworks mem usage = 276,604 pauge faults = 201,930
Hmmm......
