在Heroku應用程序中導致這些錯誤的原因是什麼？

Question

Heroku工人運行delayed_job時出現以下錯誤，但無法解決原因。第一個錯誤似乎與Evernote gem有關，儘管我實際上沒有任何代碼在整個項目中使用它。我所有的是

gem 'evernote', "~> 0.9.0" 

在gemfile中。

第二個似乎與Newrelic Heroku插件有關，這是一個應用程序監視服務。但它確實監視應用程序，所以我不知道是什麼導致了錯誤。

是什麼導致了這些錯誤？

Answer 1

我曾經得到的消息「用SIGTERM停止進程」的唯一時間一直當我已經手動終止的進程 - 例如，當我運行腳本/服務器然後點擊CTRL-C

這是一個操作系統消息，表示該進程被某人故意終止。這不是內部失敗。

我建議你和heroku人聊聊你的程序是否在做一些愚蠢的事情，然後終止它。

Answer 2

從Heroku的幫助：

R12 - 退出超時

的處理未能被髮送SIGTERM表明它應該停止在10秒內退出。該進程發送SIGKILL強制退出。

請參見： https://devcenter.heroku.com/articles/error-codes#r12__exit_timeout

看來你需要更快速的代碼。
