In these times where Rails 1.0 Release Candidates introduce memory leaks, bugs, and whatnot, you might want to lock your Rails application to a tried and tested version.
In your config/environment.rb, change your require_gem lines from
require 'active_support'
require 'active_record'
require 'action_controller'
require 'action_mailer'
require 'action_web_service'
to
require_gem 'activesupport', '= 1.1.1'
require_gem 'activerecord', '= 1.11.1'
require_gem 'actionpack', '= 1.9.1'
require_gem 'actionmailer', '= 1.0.1'
require_gem 'actionwebservice', '= 0.8.1'
require_gem 'rails', '= 0.13.1'
and you’ll be rolling on Rails 0.13.1 until you decide not to. Best way to make sure breakage doesn’t happen when your host decides to upgrade without warning you.
Ironically enough, binding your application to the current gems is a lot easier on 0.14.x. All you have to do is rake freeze_gems.
