Problems running *arr stack on Raspberry Pi (feddit.nl)

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.

Do I need to buy a more powerful device?

Yes? You seem to have answered that yourself.

Run "free" and see how much memory is being consumed. And "top" as well (hitting 'm' will sorry by memory usage).

Just checked on my pi4 with 4GB of ram that has been running beautifully as a NAS with 2x10TB USB drives mirrored, *arr suite, and Jellyfin for a couple of years, only 250mb of RAM free. I’m glad I splurged and got the 4gb model.
