On Linux, the kernel writes messages about MCEs to the kernel message log and the system console. When the MCEs are not fatal, they will also typically be copied to the system log and/or systemd journal. For some systems, ECC and other correctable errors may be reported through MCE facilities. [5] Example:
An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments.

This mechanism enables the automated handling of software errors independent of the application source code and of its developers. It is a direct artifact of the runtime engine paradigm and it enables unique advantages to the software life cycle that were unavailable before.

The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...
