Hello everyone!
On RPi i have 2Gb of RAM and running two nodes with two docker containers. Is this command still correct for both nodes? --memory=1800m
Or should i divide by 900m for each container?
It’s better to divide, however, you can try to do not limit the memory. Raspberry Pi3 is hanging when the process took all the RAM, but maybe your Raspberry is better.
I believe that the problem is in Raspberry operating system, not in the hardware 
T.y. will try to divide.
