I’m getting that message too about low RAM. Did this fix the issue, or is it still happening? Also, i’m trying to decide whether to just upgrade to an 8GB RAM RP and get it over with.
I saw that as well. I deleted a few unused apps and the message went away. I would have liked to keep LNbits, but wasn’t yet using it, so deleted it. Problem solved.
I saw one comment from someone else, saying they gave it about 12 hours, and restarted their node, and now the RAM usage is fine. Mine is too. Hovers around 50-60% most of the time, even with 2-3 apps running at once (I tried to max it out just to stress test it). I am however, upgrading to a RaspberryPi 4 8GB, just because. Bright side, I’ll have a spare Pi just in case anything happens. Or, I’ve also thought about setting up a secondary backup node.
