Heroku记录FATAL SignalException：SIGTERM [英] Heroku logs FATAL SignalException: SIGTERM
本文介绍了Heroku记录FATAL SignalException：SIGTERM的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我知道SIGTERM只是一个终止程序的信号，我不相信解决方案是处理或忽略它。
当我查看部署的网站时，它显示为白页。如何解决这个错误，以便我的应用可以正常显示？
这是我的Heroku日志：

解决方案
当一个dyno关闭时，例如作为每日重新启动或作为睡眠或新版本（如您在示例中所示），然后Heroku必须关闭在dyno中运行的进程。
这是通过发送 SIGTERM 进程。
您显示的日志与此行为一致。
的确，如果我在本地运行一个webrick服务器，并用SIGTERM（ kill -SIGTERM< pid> ），它的行为方式完全相同。

I don't understand why I am getings this FATAL exception. It works just fine in localhost.
I understand that SIGTERM is simply a signal to terminate the program, and I don't believe the solution is to handle or ignore it.
When I look at the deployed website it displays as a white page. How can I fix this error so that my app can display normally?

When a dyno shuts down, for example as part of a daily restart or as part of sleeping or a new release (as you have in your example) then Heroku has to shut down the processes running in the dyno.
It does this by sending a SIGTERM to the processes.
The logs you show are consistent with this behavior.
Indeed, if I run a webrick server locally, and shut it down with SIGTERM (kill -SIGTERM <pid>), it behaves in exactly the same way.
