Without a safety net, the kernel's out-of-memory handling starts ending processes to keep the system alive, and it doesn't always pick the process you'd have chosen. A swap file gives the kernel somewhere else to put memory pages before it gets to that point, and setting one up takes a handful of commands and about fifteen minutes. This guide creates a swap file, activates it, makes it survive a reboot, and tunes how eagerly the kernel actually reaches for it.</p>
