网卡nat模式消息队列、数据库长连接不灵
网络连接模式是nat，连接不稳，我的一个amqp收queue脚本，客户端已断而服务器上显示仍连接，凭空吃message，数据库也经常断，所以写了一个bunny短连接版

#!/usr/bin/env rubyrequire File.expand_path('../../config/environment', __FILE__)def seek_queue  queue_name = Settings.queue.packapp.ios  BUNNY.start  payload = BUNNY.queue(queue_name).pop[:payload]  if payload == :queue_empty    BUNNY.stop    sleep 5  else    conn = ActiveRecord::Base.connection    begin      conn.reconnect! unless conn.active?    rescue ActiveRecord::StatementInvalid => e      sleep 10      retry    end    # ...    BUNNY.stop  endendloop do  begin     seek_queue  rescue Bunny::ServerDownError => e    sleep 60    retry  end  end
