It is the hobby plan on railway.com. 8GB w/ 8vcpu. I used the top n8n template. ( n8n w/ worker by jack ) .
Another thing I noticed was that postgres DB spiked to 1.5 gb when I started working on my 2nd automation.
Since the issue kept on coming, eventually I wiped everything and now use another template n8n (workers + internal Redis + webhook processor) by avgsoft.
This looks stable for now
