crash in Ubuntu GNU/Linux

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"

You've been gnomed
Who uses ram anyway. Go buy yourself an HDD of 12TB of swap partition
- Cloud is the future. Mount Google Drive as your swap
- What if they have more than one pc? Are they supposed to buy a harddrive for each?
  
  Get yourself a NAS and use that for swap, much easier to share between devices!
- How do you get it to actually swap? I tried changing swapiness but it still hardly touches swap but maxes out ram and freezes.
  
  To be frank, I don't actually know. I've had one or two times where my ram was maxed out because I used too many VMs but I barely remember
100% RAM is a huge pain on Linux. I have a widget in my taskbar that always shows my RAM usage so I can tell if I'm about to get doinked
- Same, what usually spikes yours to 100%?
  
  Up until yesterday I would've said "Firefox" (because I hoard tabs), but it turns the real answer was "Firefox running as a Snap."
  
  (A failed update screwed up my Snap installation, which finally gave me the kick I needed to quit procrastinating and excise it from my system once and for all. I'm running Firefox installed via apt package from Mozilla's PPA, and now -- with the same number of tabs open -- my system is hovering around 8 GB memory usage, when before it was constantly bouncing off the 32 GB redline.)
  
  Carelessly running too many programs and not having much RAM.
  
  When I get my Framework 16, I'll either get 64 or 128GBs of RAM. It's so cheap nowadays, the only thing stopping me from getting more is simply the increased time to go to sleep and wake up.
  
  Manipulating gigantic log files can do it for me.
- There are automated memory killers that should avoid this. I'm using nohang, but systemd also has some module for this.
- Same, what usually spikes yours to 100%?
- same! I have a nice icon next to it on my i3 status bar.
- Doesn't Linux have some sort of Page File?
  
  Its not a dedicated file usually as you can setup a swap partition.
The cool part is, the kernel and most of the user space is still running fine, so there's no restart required (although I would anyway), it's just gnome is having issues.

I've had dodgy hardware cause a kernel panic, which is much more equivalent to a Windows BSOD.
- I think I made it work too much. i'm running 23.10(non-LTS), hadn't shut it down for weeks, and was hoarding close to 200 tabs. furthermore, I had 3-4 electron-based applications open.
  
  That's not a problem. Especially because modern tabs hibernate. Linux can go forever without restarting, to the point where there are multiple services cropping up that let you upgrade your kernel while it's running, so you never have to reboot (mostly, in some edge cases it's still recommended to reboot).
Failed to allocate 17.3 TiB of memory

Oooh, this blokes found a beauty! I haven't seen one of those since I used an Eee PC with Debian as my daily driver. It has a whopping 1, I repeat, ONE GIGAbyte of RAM.
- Debian is just rock solid. no matter if you use it on 1 or 16gb, it just doesn't die.
- 1gb?! Is this some kinda futuristic alien tech?
- 1 GB is fine for web browsing. Just make sure you have some swap and a SSD.
That's not a blue screen, that's a boo screen
Doesn't it show an error code?
I literary had this problem today!!! What I did to fix, and I'm not sure which one of these it is, but I ran all of these and I got it to work again

sudo apt install --fix-broken

sudo apt-get update && sudo apt-get upgrade

sudo apt install --reinstall gnome

sudo apt install --reinstall xorg

sudo apt install --fix-missing

sudo apt autoremove
My very first experience with installing Ubuntu was a complete failure because I just got constant kernal panics. This was 2007ish trying to install Ubuntu on a bondi blue iMac using CD I had ordered from Canonical.
- what do you use now?
  
  I'm still on windows on my dekstop, I have a handful of boxes running various forms of Linux but I'm mainly just here for the memes.
Is ai creating alt text now?

Also, ya no system is crash proof =(
- should I be honoured or concerned that i'm being compared to AI? I wanted it to be descriptive.
  also, facebook has been generating alt text using AI for years now. you can see the same on unsplash.
  
  Just saying that it kinda reads. Like an ai prompt
