ABSTRACT:
A system and method of verifying a dumped memory image following a crash of a computer system that includes physical memory, a system kernel, and a virtual memory system. At least a portion of the system memory, e.g., a page, is locked by pre-allocating the page to the system kernel during initialization of the computer system. The pre-allocated page is then withheld from the virtual memory system so that the pre-allocated page is not classified as swappable memory. The locked page of the memory is then seeded with a signature. Upon detecting the system crash, the seeded page of the memory, including an image of the seeded signature, is dumped to the dump disk. The content and the location of the memory image are then verified by comparing the image of the seeded signature with the signature that was seeded in the locked page of the memory prior to the system crash.
