ruby-on-rails - 是什么导致我的 Heroku 应用程序出现这些错误？

Question

当 Heroku 工作线程运行 dependent_job 时，我收到以下错误，并且无法找出原因。第一个错误似乎与 Evernote gem 有关。 ，即使我实际上根本没有任何在整个项目中使用它的代码。我所拥有的只是

gem 'evernote', "~> 0.9.0"

在 gem 文件中。

第二个似乎与Newrelic相关。 Heroku 插件，这是一个应用程序监控服务。但它确实监视应用程序，所以我不知道是什么导致了错误。

是什么导致了这些错误？

Answer 1

我唯一一次收到“Stopping process with SIGTERM”消息是当我手动终止进程时 - 例如，当我运行脚本/服务器然后按 CTRL-C

这是一条操作系统消息，表明该进程被某人故意终止。这不是内部故障。

我建议你和 Heroku 的人聊聊你的进程是否做了一些愚蠢的事情并且他们终止了它。
