Coolify randomly crashes RaspberryPi 4B+

Description

Coolify crashing raspberry pi randomly

Minimal Reproduction (if possible, example repository)

Coolify running on a RaspberryPi 4b+ with 2GB RAM, with swap added via the swap file.

Running a fairly simple nodejs app with resource limits set on my project, and the entire system randomly crashes. I have cloudflared running and that also goes down entirely. A restart of the system only fixes things temporarily.

Exception or Error

No response

i run RaspberryPi cluster for the extra servers - i don't think your RaspberryPi is strong enough.

Is this due to a lack of RAM or CPU power? What rpi(s) are you using?

So I use 3 rpi(5) - so it could be the lack of ram, as you have 4 cores in a pi, so definitely would get more rpi's with better ram, at most 4GB for each pi

Weird because I've added 5gb of swap, I'd think that'd solve it. Under normal use, my rpi seems to be only using 50% of RAM.

So swap memory is slow compared to actual ram, so even tho only 50% is used, swap under heavy loads or close to it can decrease performance, and using swap, could max out your cpus would cause it to crash and such. You ever htop in, and watch the cpus?

Yes, I have. The CPUs spiked when deploying, but were stable afterwards. But coolify still randomly crashes my rpi entirely, even rendering cloudflared useless.

I'm using a RPi 5 and a RPi 4, both Pi's work perfect 24/7 with coolify, I also have a w2 which is arguably worse/unusable. The RPi5/4 are 8gb ram models. Note that both are out of heap memory after installing (during docker build time) a second project* on them. As local dev area's its amazing.

*I mainly run full stack Nuxt projects running server side on the hosts (rpi) using node.js.

In my experience a 2gb RPi model is really only useable as monitor instance for other coolify servers. Maybe running/serving a fully HTML static app sure, i mean coolify also requires system resources besides running your app, lets not forget everything else you are running on the pi.
