Преобразуване на рейк задача, която използва Nokogiri::XML, за да използва Nokogiri:XML::SAX

Имам рейк задача, която работи чудесно на моята локална машина, след разполагане на приложението ми във VPS, тя вече не ми позволява да изпълнявам задачата.

Изпълнявам задачата с помощта на --

RAILS_ENV=production bundle exec rake db:insert_properties

и резултатът, който получавам, е --

(in /home/deployer/apps/nsrosu/releases/20131230151646)
Killed

Някой има ли идея защо може да се случва това? Проверих двойно и тройно дали XML файлът, който използвам за изтегляне на данни за задачата за рейк, съществува в правилната директория.

Освен това се опитах, вместо да използвам файл, съхраняван на сървъра, да го изтегля от външен източник, който се съхранява другаде, но nokogiri казва, че файлът не съществува, когато го опитам по този начин. Решението на всеки един от тези проблеми би било отлично :)

Също така, тук е задачата за рейк, в случай че ще помогне да се отговори на въпроси --

================================= АКТУАЛИЗАЦИЯ =============== ===================

Така че изглежда, че най-добрият подход е да пуснете това през SAX система и SAXMachine е готов да работи с Nokogiri, но документацията и за двете технологии е доста ужасна. Надявах се да получа някаква насока как да настроя задача, която прави същото, което прави моята горна задача, но използвайки SAXMachine. Моля те :)

Публикувах пример за един от XML записите по-долу --
