I remember articles of the Airbus A350 requiring reboots every N days (150ish or so?). I remember the Patriot missile system required a reboot every 24 hours or so until they fixed the software defect which caused the time counting to drift. And I'm pretty sure there are many more such cases where devices fail if kept on for too long, even in spaces where you are supposed to fill out a lot of "paper"work + jump through a lot of defined processes like in avionics, medical, or automotive field, among a good few others (safety and all that).
