Puma delete pid file in cluster mode

[le0pard]

I have:

ruby 2.1.0
puma 2.7.1

Config:

#!/usr/bin/env puma
directory '/var/www/falcon-web/current'

environment 'staging'

daemonize true
quiet

pidfile '/var/www/falcon-web/shared/pids/puma.pid'

stdout_redirect '/var/www/falcon-web/shared/log/puma_stdout.log', '/var/www/falcon-web/shared/log/puma_stderr.log'

threads 0, 8

bind 'unix:///var/www/falcon-web/shared/tmp/sockets/puma.sock'
state_path '/var/www/falcon-web/shared/tmp/sockets/puma.state'

workers 2

preload_app!

on_worker_boot do
  ActiveRecord::Base.connection_pool.disconnect!

  ActiveSupport.on_load(:active_record) do
    config = Rails.application.config.database_configuration[Rails.env]
    ActiveRecord::Base.establish_connection(config)
  end
end

After start of puma by command bundle exec puma -C /var/www/falcon-web/current/config/puma.rb it remove pid file.

Added logging in parts of code (puma-2.7.1/lib/puma/cli.rb):

 def run
      begin
        parse_options
      rescue UnsupportedOption
        exit 1
      end

      if dir = @options[:directory]
        Dir.chdir dir
      end

      set_rack_environment

      if clustered?
        @events = PidEvents.new STDOUT, STDERR
        @options[:logger] = @events

        @runner = Cluster.new(self)
      else
        @runner = Single.new(self)
      end

      setup_signals

      @status = :run

      @runner.run

      case @status
      when :halt
        log "* Stopping immediately!"
      when :run, :stop
        graceful_stop
      when :restart
        log "* Restarting..."
        @runner.before_restart
        restart!
      when :exit
        # nothing
      end

    ensure
      $stdout.puts "delete_pidfile ensure" ### THIS IS MY LINE
      delete_pidfile
    end

What I get in output of bundle exec puma -C /var/www/falcon-web/current/config/puma.rb:

$ bundle exec puma -C /var/www/falcon-web/current/config/puma.rb'
[13838] Puma starting in cluster mode...

delete_pidfile ensure
delete_pidfile ensure

How is it possible to fix this issue?
