Well other than saying that you are calling render from somewhere that you shouldn't there's not a lot more to be said without seeing what you have done.

ok This my module which in lib folder module Rakelimit def self.included(controller)

```
    controller.extend(ClassMethods)

   end

   module ClassMethods
   
    def acts_as_rakelimit
         ip = request.remote_ip 
        puts ip = local_ip
       minute= (Time.now.to_i / 60).to_i
        checks = Ipcheck.find(:first, :conditions =>["ipaddress = ? and time_min =?", ip,minute] )
        puts checks.inspect
        if checks == nil
             Ipcheck.create!(:ipaddress=>ip,:time_min=>minute,:ip_count=>1)
        else
            checks.increment(:ip_count,1).save
            if checks.ip_count >3
    
                render_404
    
       end       
        end
    end
   
     def render_404
           render :file =>"#{RAILS_ROOT}/public/404.html", :status => "404 Not Found"

These shouldn't be class methods. This is all about dealing with an individual request, which only makes sense in the context of an instance method
