Rails Stack Level too deep

Question

How can I get more information from an error like this?

=> Booting WEBrick
=> Rails 3.1.1 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
script/rails:6: stack level too deep (SystemStackError)

Answer 1

The error was only occurring in production.

When changing settings inside config/environments/production.rb , I found that setting config.cache_classes = false let me boot the app in production. Upon reviewing the commit I found the offending class.

I had created a model called Object which seemed to have interfered with the way caching works, likely overwriting a core ruby Object class.

Answer 2

It's a loop. To have more details of this, you et "config.log_level = :debug" in the config/environments/production.rb and restart your server
