What's your code?

This works:

$ cat exc.rb
require 'drb'

PATH = 'druby://localhost:9000'

class Raiser
   def do_raise
     raise RuntimeError, "Here we go!"
   end
end

case ARGV.shift
when 'client'
   raiser = DRbObject.new nil, PATH
   raiser.do_raise
when 'server'
   DRb.start_service PATH, Raiser.new
   trap 'INT' do exit end
   DRb.thread.join
else
   STDERR.puts "#{$0} client|server"
   exit 1
end

$ ruby exc.rb server &
[1] 3710
$ ruby exc.rb client
(druby://localhost:9000) exc.rb:7:in `do_raise': Here we go!  
(RuntimeError)
         from exc.rb:14
