Rake task not running - ruby

Question

Every time I call my rake task it say:
[2012-07-12 15:50:01] ERROR IOError: An existing connection was forcibly closed by the remote host
C:/jruby-1.3.1/lib/ruby/1.8/webrick/httpresponse.rb:324:in `_write_data'

I have tryed different options thinking that it could be the call to the rake task but apparently isn't, also I have tryed with Mongrel and WEBRick in case that it could be the server.
I'm using Jruby 1.3.1
The task it's not been executed.
This is part of my code:
application_controller.rb
def call_rake(task, options = {})
options[:rails_env] ||= Rails.env
args = options.map { |n, v| "#{n.to_s.upcase}='#{v}'" }
system "C:/jruby-1.3.1/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake #{task} #{args.join(' ')} start"
end
forbidden_file.rake
desc "Process CSV file"
task :process_file => :environment do
forbidden_file = ForbiddenFile.find(ENV["csv"])
forbidden_file.upload_file
end
Controller
...
call_rake :process_file, :csv => params[:files]
redirect_to forbidden_files_url
...

It's working now, I just removed the word start from the command.
system "rake #{task} #{args.join(' ')}"
