I had exactly the same problem a couple of weeks ago, and was told out that webrick (the default server) is pretty flaky in combination with new relic. I switched the app to run on unicorn (with the added bonus that performance seems better, though I have nothing to back that up), then had to add this as well to get everything working -> http://newrelic.com/docs/troubleshooting/im-using-unicorn-and-i-dont-see-any-data
If you're not using webrick then I have no idea :) -- You received this message because you are subscribed to the Google Groups "Heroku" group.
