Ruby on Rails Errno :: EPIPE破管

我知道有很多人在网上发帖，但我一直没能找到解决方案。Ruby on Rails Errno :: EPIPE破管

在我的网站未被访问超过6-8小时后，我收到Errno :: EPIPE。我读到它可能与ruby-mysql驱动程序有关，但还没有找到解决方案。这是完整的跟踪。我使用passenger和mysql在apache上的rails服务器上运行ruby。谢谢您的帮助！！！

我看到在Passenger 3.0.7，Rails 2.3.11和Rack 1.1.1下运行Redmine的行为完全相同。我已经尝试过使用各种MySQL gem（mysql，ruby-mysql，mysql2）并添加了各种额外的规范来控制Passenger的连接池空闲时间和池大小无济于事。很多人似乎遇到了这个问题，但我还没有找到一个可行的解决方案。 – 2011-08-05 04:16:28

这三个答案中的任何一个答案都是答案？如果是这样，请标记答案 – suweller 2011-12-05 16:38:43

我增加了以下内容... /应用/控制器/ application_controller.rb

before_filter :verify_connection 

def verify_connection 
    Product.verify_active_connections! 
end

（产品是我的车型之一 - 任何一个应该工作），而这个问题就走了。

我有这个错误，而与苹果推送通知的解决方法工作从http://gaveen.owain.org/2008/04/errnoepipe-broken-pipe-mysql-error-in.html解决的问题

创造条件，使用DB连接定期如卧铺线程：

Thread.new do 
loop do 
    sleep(30*60) 
    logger.fatal("ActiveRecord::Base.verify_active_connections!") 
    ActiveRecord::Base.verify_active_connections! 
    ActiveRecord::Base.connection.select_value('select 1') 
end 
end

除非有特殊你使用ruby-mysql的原因，删除它，安装'默认'mysql gem

gem install mysql2

并使用一个在你的Gemfile：

gem "mysql2"

据博赫丹Pohorilets提到博客的作者，这是问题是如何解决的。
