Timeout :: Error: время выполнения истекло при использовании Redis в Rails

Question

Я часто получаю сообщение об ошибке тайм-аута (Timeout::Error: execution expired), когда я использую Vanity, и это приводит к сбою моего сайта. Вот что происходит:

[GEM_ROOT]/gems/redis-2.1.1/lib/redis/connection.rb:19:in `connect'
[GEM_ROOT]/gems/redis-2.1.1/lib/redis/client.rb:134:in `block in connect_to'

[GEM_ROOT]/gems/vanity-1.5.0/lib/vanity/helpers.rb:52:in `track!'
app/controllers/downloads_controller.rb:80:in `go'

И в моем контроллере у меня есть:

  # GET /downloads/1/go
  def go
    @download = Download.find(params[:id])

    # Redirect & track the outbound click
    cookies[:subid] = { :value => "#{@download.to_param}", :expires => 30.days.from_now, :domain => ".example.com", :path => "/" }
    cookies[:download_type] = { :value => "#{@download.download_type}", :expires => 30.days.from_now, :domain => ".example.com", :path => "/" }    
    redirect_to @download.destination.strip, :status => :see_other
    track! :download_start
  end

Я использую Ruby 1.9 на Passenger, под управлением Vanity . Кто-нибудь знает как это исправить?

Спасибо!

ОБНОВЛЕНИЕ Некоторые люди предложили добавить это к environment.rb для обработки разветвлений в Passenger, и это все еще не решает проблему ...

# monkey patch vanity to force new redis connection when Passenger forks
if defined?(PhusionPassenger) 

  class Vanity::Playground 
    def reconnect_redis 
      @redis = nil
      # Need to remove method or unable to force a reconnect because it
      # hits the method, not the variable.
      class << self ; self ; end.send(:remove_method, :redis)
      redis # Make a new connectiont to redis
    end 
  end

  PhusionPassenger.on_event(:starting_worker_process) do |forked| 
    if forked 
      # We’re in smart spawning mode.
      begin
        Vanity.playground.reconnect_redis 
      rescue Exception => e
        RAILS_DEFAULT_LOGGER.error "Error connecting to redis: #{e.to_s}" 
      end
    end 
  end 
end
