Ruby on Rails Errno :: EPIPE Broken pipe

Sé que hay mucha gente publicando esto en línea pero no he podido encontrar una solución.Ruby on Rails Errno :: EPIPE Broken pipe

Recibo Errno :: EPIPE después de que no se haya accedido a mi sitio web durante> 6-8 horas. Lo leí sobre el driver ruby-mysql, pero no encontré una solución. Aquí está el rastro completo. Estoy ejecutando un servidor de ruby on rails en apache con passenger y mysql. ¡¡¡Gracias por la ayuda!!!

Estoy viendo exactamente el mismo comportamiento al ejecutar Redmine bajo Passenger 3.0.7, Rails 2.3.11 y Rack 1.1.1. He intentado usar varias gemas de MySQL (mysql, ruby-mysql, mysql2) y agregué todo tipo de especificaciones adicionales para controlar el tiempo de inactividad del grupo de conexiones del pasajero y el tamaño de la agrupación en vano. Mucha gente parece encontrarse con este problema, pero todavía no he encontrado una solución viable. –

¿Alguna de las tres respuestas dadas es la respuesta? Si es así, marque la respuesta – suweller

que añade lo siguiente al .../app/controllers/application_controller.rb

before_filter :verify_connection 

def verify_connection 
    Product.verify_active_connections! 
end

(productos es una de mis modelos - cualquiera debería funcionar) y este problema se fue.

Parece que todavía falla. ¡Gracias por la sugerencia! –

tuve este error mientras se estaba trabajando con las notificaciones push de Apple solución de http://gaveen.owain.org/2008/04/errnoepipe-broken-pipe-mysql-error-in.html resuelto el problema

Crear un hilo de cama que utilizaría la conexión DB periódicamente Ej:

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

menos que haya una especial razón por la que el uso de rubí MySQL, quitarlo, instalar el mysql 'default' joya

gem install mysql2

y el uso que uno en su Gemfile:

gem "mysql2"

Según el autor del blog mencionado por Bohdan Pohorilets, esto es cómo se resolvió el problema.
