Thank you for the information.

I have 2 identical (very old) Mikrotik RB2011 devices which have run 
unaltered for many years but are now flashed to OpenWrt for another purpose.

1 of the devices showed the same behaviour you described.
I will definitely try this on the broken device.

Thanks for taking the effort to share this!
