A method, apparatus, and computing system are provided for self-healing from a fault in an operating system (OS) without crashing the OS. In one example, the method includes detecting, isolating, and repairing a faulty kernel code module without affecting the run-time operation of other, properly function, portions of the OS. In another example, the apparatus comprises a variety of modules, including, for instance, a kernel level fault detector and a kernel level fault manager, that are configured to execute steps of the method. In another example, the computing system includes an OS that has at least some modularized kernel code sections, and a self-healing code for detecting, isolating, and repairing failures occurring in one or more of the modularized kernel code sections without crashing the OS.
