Also, I've seen it run higher, but usually not too bad on Ram.
It turns out I like the privacy and stablecoin $L-USDT features of nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n Liquid Network.
I have the option to run a Liquid full node on my Umbrel, but it requires up to 6GB of RAM.
I might wait until I get a new 16GB nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct home server to replace my 4GB Pi 4 in a months time.

Interesting, I've seen Bitcoin Core and also Lightning consume more than that on occasion.
I really wanted Umbrel to build a 32GB RAM node, but maybe 16GB will be OK.
Thanks
