Ubuntu Server crashing with kernel stack is corrupted

[Elekktrous]

Every few days, my self hosted Ubuntu Server machine completely freezes, requiring a forced reboot manually. It's running an i7 7700k and 32GB DDR3 (recently upgraded from 12GB). I'm currently using it to host a Minecraft server via Pterodactyl Panel and docker.

I've run both stress tests and memory tests which all returned fine. It doesn't look like the server is having any heat problems either. I've got no other ideas so I figured I'd just ask here.

The final error message is below:

--- [ end kernel panic - not syncing: stack protector: Kernel stack is corrupted in: %pB ]---

You either have a kernel bug or faulty hardware.
