Thanks guys.
What I don’t understand is that I had 2GB RAM and it was working well, then suddenly I started to have a high load average. I already upgraded to 4GB RAM and I am still facing the same issue, how is it possible that Discourse suddenly needs so much more RAM?
I also changed my app.yml with UNICORN_WORKERS: 3, it was 8 before.
I am rebuilding the app now and I’ll check if there is any changes.
