Hi Thomas,

8G of RAM (without swap) on a Pi4 should be sufficient ;-)

------------------<8------------------
root at moon:~# free -h
        total   used   free   shared  buff/cache  available
Mem:   7.6Gi   62Mi  7.1Gi    0.0Ki       409Mi      7.4Gi
Swap:     0B     0B     0B
------------------8>------------------

5.5.10 runs well, but slow on the Pi zeros (512MB).

OOM should be logged via kernel/dmesg? But there is nothing logged....
