Virtual Machine: Out of memory: Killed process 1017513 (python3)

I have Home Assistant running on a VirtualBox virtual machine on a 2015 i7 laptop and 6GB of RAM assigned

Yesterday night at 22.31 I received a notification that home assistant had restarted
It had been running smoothly for about 2 weeks now

I found this error on the virtual machine window, but I am not sure if it’s related as I don’'t usually look at it every day

The restart (or at least the setup after restart) happened at 22:31, I am not sure how long it went down for, but I guess at least 20 minutes as I have an automation that prints some quantities to a file every 10 minutes and it’s missing a few lines between 22:00 and 22:40 (highlighted in bold)

I have the same problem, did you ever figure out what was causing it?

Hi, I have the same problem.
HA running on vmware workstation (4GB ram) and “out of memory: killed process 880184 (python3)”

1 Like

From what ive figured out so far, seems like the computer doesnt have enough RAM for what the VM is trying to use. Decreasing the amount of ram my VM has seems to have fixed the problem (for now). Its been working fine for a couple of days now.

decreasing? you run out of ram and you have decreasing it? i have the same problem and i am in search for a solution.

The problem came back after a while. I tried everything, and ended up just giving up on running Home Assistant in a VM. None of the solutions I found worked. Running HA in a VM made Z-Wave, ZigBee, and Bluetooth a lot more complicated anyway.

Where are you running home assistant now?
For me is a daily problem now.

I am running it on a Raspberry PI 4; I have had random restarts since then but they seem to have stopped once I installed a cooling kit

I’m using a cheap mini PC that I got for $180, similar to an Intel NUC. The performance seems to be pretty good, and these days it’s not much more than a Raspberry Pi 4, but it’s more powerful.

The same is here with 2022.08. It crashes every 20 mins with 8Gb of RAM.

any solution to troubleshoot this.
for me this never was a problem until the 2022.12 release

I increased from 4GB to 6GM but I don;t think that will solve it.
There is obvious some memory leak here

Is this under investigation by the HA developers ?
I also have this issue for quite a long time and still couldn’t find anything that might lead to a memory leak. Looks indeed like it is in HA itself since the new 2022.12 version.
I now have an automation created to call for a service to reboot every day at night.

happens here too,since around then in time before i started noticing and have to reboot regularly i did swap the hyperv vm between two computers i thought it maybe hardware related and try to place it back, but now iam not sure

Hey guys,
I have actually the same problem. My ha instance is running for ~10 minutes, then i gets an error, see screenshot below:
My proxmox vm has 8vGB of RAM, 2xvCPU cores (host: AMD Ryzen 7 3700X) and 32 GB of vHDD
first i had 2022.12 version, today i upgraded to latest 2023.x version and error still appears.


What can i do to fix this error and get my HA back to life??
