Your associations are incorrect. Both Role and CriticalProcess refer to each other via has_many -- one of them must use belongs_to. And where is the Authorization class? What is it's relationship to CriticalProcess?
Fix the associations problem and the loop will likely go away. Why? I suspect because the CriticalProcess has_many :roles implies that Role belongs_to it. Thus, ActiveRecord creates its own create_roles for you. See http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html#method-i-has_many. Notice the methods you get for free with each kind of assocation. Nothing will work the way you have it defined now.
