I've installed "Armbian buster with Linux 5.4.49-rockchip64" on my nanopim4v2, straight to SDCard. I ran apt update and upgrade. Then used the install script for ARM devices and everything went fine.
I've been able to login to the webUI fine. I created 1 user. Then I created 2 shares. One temporary test share for SMB. One for Docker and any containers. I set the path for Docker. Then installed Docker and Portainer all using the WebUI. All working great.
Now to problem. I simply leave the system on (doing nothing) over night and next morning a see the 'heartbeat' light flashing away. I wondered why so SSH in and ah... high system load, but low CPU. I don't know how to tackle this but I've tried to include some info below. Let me know what else you might need in order to suggest something. Thanks, any help appreciated.
BTW this is a totally clean install. I've wiped the SDCard, followed ARM install guide and the result is the same, it's fine initially but after some times (hours) the system load ramps up and up.
