Hello everyone, I have a Raspberry Pi 4B with 2GBs of RAM. I am trying to run all the *arr stack via docker containers(5 or 6 containers) but this causes my Raspberry Pi to lag very much. I could not use any of the stack’s web interface or SSH to the pi during the lag and to fix it I had to reset the pi.

I think it is because I have little RAM but it might also be the power supply because I sometimes get messages for undervoltage.

What do you think is happening and how could I fix it? Do I need to buy a more powerful device?

Thanks in advance.

    Agree! I had arr stack + nextcloud on rpi4 4GB and it was using bit less than 3GB after restart, but after some time it would hit 4GB and start using SWAP and I would have issue just like OP. Solved that by moving server to DIY PC with 8 GB, but then I added many more services and had to upgrade to 16 GB. Sitting at 4+GB free RAM all the time while using 40+ services
