Hello everyone, I’ve been trying to upgrade my Home Assistant setup on my Raspberry Pi 4 with 4GB RAM, but I keep running into issues. Whenever I attempt to upgrade Home Assistant OS beyond version 11.1 or the core beyond 2024.11.3, the system crashes with an Out of Memory (OOM) error. After rebooting, I see multiple OOM kills in the logs, which is pretty frustrating.
I’ve checked the memory usage before starting the upgrade, and it shows about 2.3GB free. Here’s a snapshot of the memory status:
$ free -h
total used free shared buff/cache available
Mem: 3.7Gi 801Mi 2.2Gi 1.3Mi 920Mi 3.0Gi
Swap: 1.2Gi 0B 1.2Gi
I’m wondering if this is expected behavior or if there’s something I can do to resolve this without upgrading to a more powerful Raspberry Pi. Has anyone else encountered similar issues, and if so, how did you overcome them? Any advice would be greatly appreciated!
