Help diagnosing server freeze issue (piefed.social)

I’ve been experiencing some perplexing and frustrating issues with my server, and need some advice from those more knowledgeable than me.

Recently I decided to upgrade my raspberry pi server and I found a good deal on an HP Elite Mini 600 G9 on eBay so I took the plunge. It’s got an Intel Core i5-12500T and came with 8gb ram and a 256 gb ssd. I bumped it up to 32gb ram and added a 4tb ssd. It came with windows installed but I installed Debian on there.

With the basics taken care of I got setup with my couple of docker containers (if it matters: caddy, actual budget, immich, prometheus, grafana). But ever since then, anytime some CPU-heavy process runs, the whole machine freezes and stays frozen (I’ve tried letting it go to see if it recovers but it stays frozen for days), and I am forced to physically power it down. I tried to isolate it, thinking it was one of the docker containers but it happened with immich, prometheus, & grafana individually, as well as a borg backup running directly on the machine. When I power it back on after one of these freezes there are not even any system logs from the entire period of the freeze, so I can’t learn anything from them to indicate the issue.

Anyone have any ideas what the issue could be or even where to look? I’m starting to think it’s a hardware problem but I’m not sure and I don’t know what my next step should be.

CPU-heavy process

Sounds to me like a hardware issue: you're overheating. Find a way to monitor your temps. I'm not sure how to do this on Linux, so I'm open to suggestions too.

This was my first thought too.
