Newbie question regarding memory usage

I just installed 1.29 on two relays and a bp (testnet). Everything appears to be running fine. Here’s one of the relays:


I checked the memory usage (8GB RAM installed) and this is the result:


I expected the available RAM to be almost nil due to the increased memory requirements. Can someone explain why there is 6.5 GB available? Thanks!

sudo systemctl status cardano-node
or type top

what do you see?

and if you type journalctl -e -f -u cnode

yeah, I don’t know why it’s showing so less RAM :slight_smile:

It just shows the reboot cycles from the topology updater. Note that this is a brand new 1.29 relay on the testnet. I’ve not even registered the new block producer node yet although it is running (remember I said newbie :slight_smile: However, I’ve been running two relays and a bp on the testnet (1.27) for over a month with no memory issues. I appreciate your responses Alex. You’re really doing yeoman’s work here.

Also note that I added 8GB of swap since I originally started the thread. I left the swappiness at the default 60.
