I got a warning that my node was low on RAM. I have 8GB, and over 7GB was in use. LND is taking up 4GB currently.
This is the RAM panel in settings, and it looks like it is not calculating total RAM usage correctly:
I’m having the same issue.
I am out of RAM. It may be time to land Orville and upgrade the machinery. As it is, I cannot have much more than Bitcoin, LND and RTL running on 8GB.
