Im having persistent issues with Out of Memory issues killing my VM and occasionally a docker container. Fix common problems suggested I ask for additional help here, as I am running out of ideas.

Its a 32gb system with only one VM (12gb given) and only 17 running docker processes, only a few even occasionally do much.

I have seen some post about '-m 4GB' in extra parameters as one thing to try and another messing with hugepages, but I am unsure on either. I could maybe also reduce the VM down from 12gb to 8gb, I dont think it would be a problem its just running HAOS with a handful of addons

That should not need more than 2-4GB.

Can install something like Beszel to log container memory usage for a day or 2 and look at what the usage is like.

If I had to guess based on the processes running at the time, I'd say it was immich. Dump the result of ps -auxf to a file and post it, taking care to remove any passwords if they are included in your container's startup commands

ps -auxf > ps.txt

Yeah HAOS say its usling 3GB most of the time, unraid says the VM is at 7ish.

VMs will use almost everything you give them for caching that's usually pointless, so you don't want to give more than necessary.

Ok, you can use it to find out what's spawning the gunicorn and ruby processes, and either limit the RAM to that container or reduce your VM's allocation. Since the reaper is killing the VM each time (it's the largest consumer at the time the host starts to OOM), that would indicate that you just don't have enough RAM to run everything, so you can either add more (in this economy!?!) or reconfigure your services.

Once you've done all that, you can re-boot to clear the log so FCP stops warning you
