Ruby on Rails URI :: InvalidComponentError不斷崩潰服務器

Question

我的Rails服務器在某些請求中反覆崩潰，我無法在其執行條件下進行復制。這是最近一次的日誌條目。

我不知道是什麼原因造成的。絕大多數請求不會造成問題。

production.rb：

Rails.application.configure do 

    config.cache_classes = true 

    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 

    config.serve_static_files = true # ENV['RAILS_SERVE_STATIC_FILES'].present? 

    config.assets.js_compressor = :uglifier 
    config.assets.digest = true 

    config.log_level = :debug 
    config.i18n.fallbacks = true 

    config.active_support.deprecation = :notify 

    config.log_formatter = ::Logger::Formatter.new 

    config.active_record.dump_schema_after_migration = false

在項目中只是找到（用你喜歡的IDE）localhost:。 host應該只是主機，而不是最後帶有:的主機。
