this is the first time in many years of my GNU/Linux journey that I saw a BSOD. on my office machine BTW. personal machine has never crashed even once.
the crash was due to 100% RAM and swap usage.

a mobile-clicked photo of a laptop screen. the background is full black with a sad computer image in the middle. the text below it reads: “Oh no! something has gone wrong. A problem has occurred and the system can’t recover. Please log out and try again.”
just below it is a small button with the text “log out”
Its not a dedicated file usually as you can setup a swap partition.
Technically you can create a fixed size pagefile in your disk and mount it as swap workout repartitioning. But Linux doesn’t use swap much regardless of method.
It only uses swap under memory pressure. You can configure your swappyness if you want it to be more aggressive
