How to find out why rails app uses a lot of memory?

I am using Heroku and today I started seeing a lot of Error R14 (Memory quota exceeded) errors. What is the best way (or tool) to track this down and find what uses up all memory?

Install New Relic. Here you go: https://newrelic.com/.

Also, you probably want to check that you are not loading a lot of stuff via Active Record. For example, doing a Comment.all is probably not a very good idea if you have, say, 10000 comments. Instead, do something like Comment.find_in_batches which is slightly more memory friendly.
