resque工作进程在启动后不久退出，没有输出

Question

我正在尝试让resque在生产中工作。我有以下的上帝文件：

rails_env   = ENV['RAILS_ENV']  || "production"
rails_root  = ENV['RAILS_ROOT'] || "/home/rails/current"
num_workers = rails_env == 'production' ? 5 : 2

num_workers.times do |num|
  God.watch do |w|
    w.dir      = "#{rails_root}"
    w.name     = "resque-#{num}"
    w.group    = 'resque'
    w.interval = 30.seconds
    w.env      = {"QUEUE"=>"add_feed,update_all,update_feed", "RAILS_ENV"=>rails_env}
    w.start    = "rake -f #{rails_root}/Rakefile environment resque:work"
    w.log      = "#{rails_root}/log/#{w.name}.log"

    w.uid = 'rails'
    w.gid = 'rails'

    # restart if memory gets too high
    w.transition(:up, :restart) do |on|
      on.condition(:memory_usage) do |c|
        c.above = 350.megabytes
        c.times = 2
      end
    end

    # determine the state on startup
    w.transition(:init, { true => :up, false => :start }) do |on|
      on.condition(:process_running) do |c|
        c.running = true
      end
    end

    # determine when process has finished starting
    w.transition([:start, :restart], :up) do |on|
      on.condition(:process_running) do |c|
        c.running = true
        c.interval = 5.seconds
      end

      # failsafe
      on.condition(:tries) do |c|
        c.times = 5
        c.transition = :start
        c.interval = 5.seconds
      end
    end

    # start if process is not running
    w.transition(:up, :start) do |on|
      on.condition(:process_running) do |c|
        c.running = false
      end
    end
  end
end

但是，当我尝试运行上帝时，我得到了以下输出：

基本上，resque每隔几秒钟就退出一次。我没有日志输出，没有错误，什么都没有。

Answer 1

我在我的开发环境中遇到了同样的问题，运行

QUEUE=* bundle exec rake resque:work

将直接退出到命令行。我不得不和VVERBOSE=1一起跑来搞清楚到底是怎么回事。对于我来说，我得到了以下错误：

Failed to start worker : #<NoMethodError: undefined method `auto_flushing=' for #<ActiveSupport::Logger:0x00000108908ab8>>

事实证明，在我们的项目中

Resque.before_first_fork = Proc.new { Rails.logger.auto_flushing = 1 }

在我们的resque.rake文件中的resque:setup任务中。
