Supervisor running a single core at 100% CPU

Installation
1

Hi All!

I face the problem that on my Virtual Machine based installation Supervisor is constantly running at 100% consuming a full CPU core. Updating to Core 2025.5.2 and Supervisor 2025.05.1 did not solve the problem. Sadly i cannot say when the problem started but on 2025.5.1 it definitely was already there. I checked supervisor log and found a few log entries regarding wrong configuration of the Zigbee2MQTT addon but solving them also brought no solution.

Can anyone point me into a next debugging step?

Thanks + best regards

Michael

You could start by telling what hypervisor, and what resources you allocated to HA.

Sure - I am using Proxmox VE 8.4.1, HA Virtual Machine has 8GB of RAM, 4 Cores and 100G of disk which was always plenty :slight_smile:

Maybe addon vscode?

i saw that but the process taking the CPU load in my case is actually python3 -m supervisor:

Just for whom this might be interesting. I managed to see it happening and the root cause seems to be that the Samba share i use for storing my backups got full. That somewhat upset the supervisor into the 100% CPU usage
