使用ruby機械化gem時發生SSL重用錯誤

Question

在出現以下錯誤之前，我的機械化腳本運行了大約3個小時：

C:/Ruby193/lib/ruby/gems/1.9.1/gems/net-http-persistent- 
2.7/lib/net/http/persistent/ssl_reuse.rb:29:in `initialize': 
A connection attempt failed because the connected party did not properly 
respond after a period of time, or established connection failed because
connected host has failed to respond. - connect(2) (Errno::ETIMEDOUT)

我認為這是因為它已經運行了2-3個小時，但我想知道是否有人對此錯誤有任何特殊的見解

這是我的劇本

require 'rubygems'
require 'mechanize'

def next_button(web_page)
  web_page.page.search('.next a').each do |next_button|
    web_page.click(next_button)
    web_page.page.search('.listing_content').each |info|
      get_info(info)
    end
  next_button(web_page)
  end
end

def get_info(info)
  infos = info.at_css('.url').text.strip
  address = info.css('.street-address').text.strip
  city = info.css('.locality').text.strip
  state = info.css('.region').text.strip 
  zip = info.css('.postal-code').text.strip
end

web_page = Mechanize.new                     
web_page.user_agent_alias = "Linux Firefox"
web_page.get(HOME_URL)

web_page.page.search('.page-navigation a').each do |pagination_link|
 web_page.page.search('.categories-list a').each do |link|  

    web_page.click(link)
    web_page.page.search('.listing_content').each do |info|  

      get_info(info)
    end
    next_button(web_page, worksheet)
  end

  web_page.click(pagination_link)
end    

感謝您的任何幫助。

在我看來，持久連接比它們值得的麻煩更多。 當發生這種情況時，我會檢查以確保我具有最新版本的機械化，如果仍然發生，我會退回到機械化1.0.0，它不使用持久連接。
