connect to DRb server from rails controller ?

I haven't done any DRb stuff in awhile, but I used to connect to a DRb
server from
a rails controller. I've never tried it in rails 3 and am wondering if
Rails 3 is stricter about something like this or why it hasn't worked
thus far.

My server/client code and error are shown below:

SERVER:

require 'drb'

class ParserSvc

  def initialize

  end

  def check
    return 'ok'
  end

end

svc = ParserSvc.new

DRb.start_service 'druby://:9000', svc
puts "Server running at #{DRb.uri}"

trap("INT") { DRb.stop_service }
DRb.thread.join
