In the system logs I found several restarts of audio, cli and dns (same as for SSH addon).

In portainer I found the error was caused by
exec: fatal: unable to exec bash: Exec format error
I’m not so sure what was done with the armv7 images - but I was able to workaround by installing armhf images as armv7. Is it only me - or do the armv7 no longer work with raspi 4?
