CasaOS instability on debian 12?

[DonkerLukas]

Hi all,
I´ve installed CasaOS on a MiniPC (brand new) with debian 12. For a long time i had no problems add all.
Since i´ve used paperless-ngx more, the minipc shuts down once in a while. There is no fixed time he does that, there is also no interaction necessary... It will shut down on it´s own with no logged in user, neither in casaos nor paperless.

I´ve unexpirienced with debian. Has somebody more expierierience and can supply some good commands to investigate?
Maybe have some more knowledge about debian?

I assumed somethling like a OutOfMemory Error...so i reduced the usable RAM of the containers. But the server seems still crashing.
Drive, temparatures and RAM seem fine on idle.

I had something like that today. I booted from a usb drive to run SpinRite on an external drive, I set it to run and left the house and when I got home the power light was on but it was not responsive to the keyboard and there was nothing on the monitor.

Forget it, i´m just dumb. I have forgotten that linux not only has hibernate but also suspend.

I disabled suspend and hibernate with this command:

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

After this my system runs perfectly stable.
