How to daemonise Ruby AGI app.

ruby-agi-daemon.rb

#!/usr/bin/env ruby

# NOTE - Following code was tested with AsteriskRuby gem and Adhearsion v. 1.2.3

require 'rubygems'
require 'pp'
require 'monitor'
require 'timeout'
require 'time'
require 'AGIServer'
require 'daemons'

class YourAGIAppClass
  # ...
  
  class << self
    def start
      begin
        unless defined?(@@server)
          @@logger = Logger.new(STDERR)
          @@logger.level = $in_debug_mode ?  Logger::DEBUG :  Logger::FATAL
          @@server = AGIServer.new :bind_port => 30303, :bind_host => '127.0.0.1',
            :min_workers => 2, :max_workers => 2, :jobs_per_worker => 2,
            :logger => @@logger, :stats => false
          @@server.start
        end
      rescue => err
        pp err.backtrace
      end
    end

    def stop
      begin
        sleep 10
        @@server.shutdown if defined?(@@server)
        puts "CALL SERVER STOPPED!!!"
      rescue => err
        pp err.backtrace
      end
    end
  end
end

def daemonize
  daemon_specs = { :dir_mode => :normal,
    :dir => "/var/log/asterisk/", # directory where pid file will be stored
    :backtrace => true,
    #:monitor => true,
    :log_output => true
  }
  Daemons.run_proc("call-logger", daemon_specs) do
    YourAGIAppClass::start
    trap("INT") { CallServer::stop }

    loop do
      sleep CHECK_INTERVAL
      YourAGIAppClass::do_periodic_taks
    end
  end
end

daemonize

It seems like missed @@server.finish after @@server.start
