I have this in production with "rpm_contrib", "2.1.8" and "newrelic_rpm", "3.3.3". What's on the stack?
Sorry, was my fault.
i used both:
extend NewRelic::Agent::Instrumentation::Rack
AND
extend NewRelic::Agent::Instrumentation::API
Now i only use extend NewRelic::Agent::Instrumentation::API and it works fine.
We no longer use this instrumentation and have reworked it. Check out [this blog post](http://artsy.github.com/blog/2012/11/29/measuring-performance-in-grape-apis-with-new-relic] for details.

Thanks for the snippet.
I get a stack level too deep, though.
The only additional information i get is: actionpack (3.2.2) lib/action_dispatch/middleware/reloader.rb:70
I followed your instructions and tried it with newrelic_rpm 3.3.4 and 3.1.2....both end up with stack level too deep.
I use ruby 1.9.3p125 and rails 3.2.2
Any ideas?
