SYMPTOMS
Your Microsoft Windows 2000 Server-based computer crashes and you receive the following Stop error message:

STOP 0x0000001a (0x00041284, 0x797d6000, 0x000331ba, 0xc0881000)

Note The four Stop error parameters may vary.



CAUSE
This problem may occur if Physical Address Extensions (PAE) is enabled on your computer and you are running a PAE-aware program. If PAE is enabled, the virtual memory manager may split a page table entry (PTE) read operation into two unsynchronized 4-byte read operations. This split may cause PTE corruption to occur.
