I just ran it on my desktop. I can’t replicate. Here’s what I see:
root@shinytim:/var/discourse# ./discourse-setup
Ports 80 and 443 are free for use
'samples/standalone.yml' -> 'containers/app.yml'
Found 33GB of memory and 8 physical CPU cores
setting db_shared_buffers = 4096MB
setting UNICORN_WORKERS = 8
containers/app.yml memory parameters updated.
