rails + unicorn + nginxおよび を使用しcapistranoて展開するアプリケーションがあります。
昨日バンドルの更新を実行するまで、すべて正常に機能していました。メソッドが見つからないため、ユニコーンサーバーが突然起動できなくなりました。generated_attribute_methods
開発中は問題なくサーバーを起動して使用できますが、本番環境ではこのエラーが発生します
これは、rvm (本番) を使用する私のマシンからのサーバー起動からの出力です。

カピストラーノでルビー1.9.3-p392を使用するように設定したため、これは奇妙ですが、ubuntuであり、機能していたため、これがどのように問題になるかわかりません
ここで何が問題なのですか？私は何をすべきか？

必要に応じてconfig.ru
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
run Webapp::Application

サーバーを起動するために使用しているコマンドは、基本的に次のとおりです。
bundle exec unicorn -p 3000 -c ./config/unicorn.rb -E production
そして、私がに変更した場合
bundle exec unicorn_rails -l 0.0.0.0:3000 -E production
それは機能しますが、サーバー内に構成を入れていません。さらに、unicorn_railsもう使用すべきではないことを読みました

どうやら私の問題は内部にありますWebapp::Application.initialize!
puts "before" # => prints
Webapp::Application.initialize!
puts "after" # => don't prints

私は他のマシンと私のサーバー（ubuntu 10.04）と私のマシン（mac os x）でテストしていましたが、サーバーが起動せず、そのエラーが発生しました。しかし、同僚のマシン (ubuntu 12.04) では問題なく動作します。
そして、いくつかのテストの後、開発コードをクリーンアップし、git から最新バージョンをダウンロードすることにしました。今では正常に動作することもあれば、エラーが発生することもあります。
どうなり得るか？

どうやらこれは new relic + unicorn が原因で、次の行にコメントしています:
if defined? Unicorn
::NewRelic::Agent.manual_start()
::NewRelic::Agent.after_fork(:force_reconnect => true)
end
すべてを正常に動作させる
