工人 puma 日志的提前终止是什么意思，为什么会发生这种情况？

Question

对于我的 Elastic Beanstalk 实例，504每当我访问它时都会收到状态代码响应。当我跟踪日志时，我会在 puma 应用服务器上看到以下日志：

==> /var/log/puma/puma.log <==
[27240] Early termination of worker
[27245] Early termination of worker
[27249] Early termination of worker
[27253] Early termination of worker
[27257] Early termination of worker
[27261] Early termination of worker
[27265] Early termination of worker
[27269] Early termination of worker
[27273] Early termination of worker
[27277] Early termination of worker

是什么Early termination of worker意思，为什么会发生？此外，日志是否可以指出我在远程环境中面临的超时错误的原因？rails 应用程序和 puma 在我的本地机器上完美运行（Mac OS Catalina 10.15）。但是，在如上所述的远程 Elastic beanstalk 环境中，我收到超时 504 错误，并且我在日志中看到的唯一内容是上面的 puma 日志。

这是我的 gemfile：

git_source(:github) { |repo| "https://github.com/#{repo}.git" }

好吧，这需要大量的调试并深入很多不同的兔子洞。问题非常简单。我创建了一个拼写错误的类，并将其命名为GetLitsingsResponse. 将类更改回GetListingsResponsePuma 后，在我的远程 AWS Elastic beanstalk 环境中工作得很好。这很奇怪，在我的 Mac OS 本地 Puma 上没有问题。但在运行 Ruby 2.6 (Puma) 的 64 位 Amazon Linux 2018.03 v2.11.4 平台上 Puma 将无法正常运行。
