如何解決Rails中執行過期錯誤？

Question

我有一個與獨角獸服務器Heroku的Rails網站。我偶爾會通知我的錯誤，如下列之一：

ActionView::Template::Error: execution expired
(in /app/app/assets/javascripts/application.js)

這是我的application.js文件：

//= require jquery 
//= require jquery_ujs 
//= require bootstrap 
//= require_tree 
//= require jquery.qtip.js 

日誌不能清楚地指明是什麼原因導致這樣的錯誤的錯誤。例如，最近的日誌如下所示。什麼可能導致這樣的錯誤，或者我應該如何診斷它們？

獨角獸配置：

# config/unicorn.rb 
worker_processes Integer(ENV["WEB_CONCURRENCY"] || 3) 
timeout 15 
preload_app true 
#... 

抓超時：

#timeout.rb 
Rack::Timeout.timeout = 13 

日誌：

如果這實際上是通過渲染的application.js引起的，你可能設法關閉資產預編譯，因爲否則該文件將被預編譯，只是一個文件來服務哪個可以幾乎沒有時間了。

檢查資產預編譯並重新啓用它，如果它真的被禁用。

如果情況並非如此，文件可能非常龐大，如果您實際使用JavaScript資源文件夾中的所有內容，則應重新考慮。
