斷開數據庫連接在運行魯弗斯調度

我收集在線設備/臺服務器上，在每天在12爲此，我已經在我的控制器的書面工作。目前我用。在方法進行測試。這裏是我的控制器代碼

require 'rubygems' 
require 'rufus/scheduler' 
require 'net/ssh' 
require 'fileutils' 
require "time" 
require "date" 

scheduler = Rufus::Scheduler.new 

scheduler.at '2014/05/09 9:35:00' do 
    autoupdates = AutoupdatesController.new 
    autoupdates.get_all_online_units 
end 

class AutoupdatesController < ApplicationController  
    def get_all_online_units 
    # logic for getting online units 
    end  
end

調度程序運行良好，但它斷開我的數據庫連接。此外，我檢查了是否我剛剛初始化調度程序對象，那時它也在剎車。它給出無法連接到MySQL服務器錯誤。重新啓動服務器後，它工作正常。

對此，我正在使用rails 3.2.11, ruby 1.8.7 and rufus-scheduler 3.0.7 如何解決此問題。

編輯現在我已經在config/initializer/task_scheduler.rb創建一個單獨的文件。這裏是我的文件內容

require 'rubygems' 
require 'rufus/scheduler' 
require 'net/ssh' 
require 'fileutils' 
require "time" 
require "date" 

scheduler = Rufus::Scheduler.new 

scheduler.at '2014/05/08 1:25:00' do 
    Rails.logger.info("#-----------In the config/initializer/task_scheduler.rb-----------#") 
end

然後開始它給我相同類型的錯誤

    from /home/pdcadmin/deploy/pdc-dashboard/config.ru:0:in `new' 
    from /home/pdcadmin/deploy/pdc-dashboard/config.ru:0

然後我評論從task_scheduler.rb文件下面一些行服務器後是該文件

require 'rubygems' 
require 'rufus/scheduler' 
require 'net/ssh' 
require 'fileutils' 
require "time" 
require "date" 
=begin 
scheduler = Rufus::Scheduler.new 

scheduler.at '2014/05/08 1:25:00' do 
      Rails.logger.info("#-----------In the config/initializer/task_scheduler.rb-----------#") 
end 
=end

並再次啓動服務器，它工作正常。

編輯2這裏是我的config.ru文件

# This file is used by Rack-based servers to start the application. 

require ::File.expand_path('../config/environment', __FILE__) 
run MyApp::Application

rufus-scheduler不會斷開與數據庫的連接。看看它的源代碼，你將看不到有關數據庫連接的信息。請重新解釋您的問題，特別是其標題。 – jmettraux

我已更改標題。 – user2622247

文本不清楚。什麼時候發生「無法連接到MySQL錯誤」？你能否添加完整的錯誤跟蹤？ – jmettraux
