Large amount of records brings error

That 'blah blah' probably tells you what went wrong. Without the details of what errors you're getting it will be hard to suggest a fix.

Fix your configuration so that you get the actual exception been through with stack trace etc... and you'll find problems a lot easier to fix (config.action_controller.consider_all_requests_local in development.rb, production.rb etc... do this)
