Если у вас нет особых причин использовать ruby-mysql, удалите его, установите mysql gem по умолчанию 

gem install mysql2

и используйте его в своем Gemfile: 

gem "mysql2"

По словам автора блога, упомянутого Богданом Похорильцем, именно так и была решена проблема.

Я добавил следующее в ... / app / controllers / application_controller.rb 

before_filter :verify_connection

def verify_connection
  Product.verify_active_connections!
end

(Продукт - одна из моих моделей - любая должна работать), и эта проблема исчезла.

У меня была эта ошибка, когда я работал с обходным приемом push-уведомлений от Apple http://gaveen.owain.org/2008/04/errnoepipe-broken-pipe-mysql-error-in.html решена проблема

Создайте спящий поток, который будет периодически использовать соединение с БД. Например: 

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
...
