make the swap space bigger

https://wpitchoune.net/tricks/raspberry_pi3_increase_swap_size.html

[CyruS1337]

@sdetweil Ok, I did. I’ll watch that. Can you explain in one sentence what I just did here or where the mistake was?

[sdetweil]

@CyruS1337 by default, the raspberry pi OS uses physical memory… if it runs out, it will try to swap out things not being used to make room for current work. but… the swap space is very small, only 100 meg…
so the swap out fails, and the current process is killed

[CyruS1337]

Ok, thanks for the explanation :) I can understand that reasonably. You are a genius

[sdetweil]

@CyruS1337 no… it happened to me!

[CyruS1337]

Now I thought it was solved, but after about 1 hour the screen was black again. I had to stop the MagicMirror with pm2 stop 0 and then restart it with pm2 start 0.

I also changed the size from 100 to 1024.

What else can it be?

sudo dphys-swapfile swapoff
sudo nano /etc/dphys-swapfile / (changed size 1024)
sudo dphys-swapfile swapon

[sdetweil]

@CyruS1337 and rebooted after changing swap file

I have now reboot the mirror …
