1. A method comprising: receiving historical processing data including information indicative of historical processing executed by a computer system, with the historical processing including a first backtracking error; determining, by machine logic and based on the historical processing data, a first important page that caused the first backtracking error by being absent from kernel memory space; establishing a first machine logic-based rule, with the first machine logic-based rule including a first triggering condition and a first consequential responsive action; determining that the first triggering condition has occurred; and in response to the determination that the first triggering condition has occurred, performing the first consequential responsive action; wherein: the first triggering condition is that the first important page of the computer system has been paged out of kernel memory space and is currently paged into paging memory space; and the first consequential responsive action includes the following: paging the first important page from paging memory space back into kernel memory space.
