Early termination of worker puma log是什么意思,为什么会发生这种情况?

问题描述 投票:1回答:1

在我的Elastic Beanstalk实例中,我收到了一个 "早期终止 "的日志。504 状态码响应,每当我访问它。当我跟踪日志时,我在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

What does Early termination of worker 是什么意思,为什么会发生这种情况?此外,这个日志是否表明了我在远程环境中所面临的超时错误的原因?rails应用和puma在我的本地机器(Mac OS Catalina 10.15)上运行完美。然而,在我的远程Elastic beanstalk环境中,如上所述,我得到了一个超时504的错误,而我在日志中看到的唯一东西是上面的puma日志。

这是我的 gemfile。

我的情况的问题是使用的puma的补丁版本不同。

要点是AWS Elastic Beanstalk使用的是 puma 4.3.3 在我使用 puma 4.3.5.

不得不修复版本的 puma 在我的Gemfile中使用的正是 4.3.3 匹配AWS Elastic Beanstalk使用的堆栈,以防止这个错误。

更多细节请见 我的这个回答 的类似问题。

好吧,这花了很多调试,走了很多不同的兔子洞。问题非常痛苦地简单。我创建了一个我拼写错误的类,并将其称为, GetLitsingsResponse. 在把班级改为 GetListingsResponse Puma在我的远程AWS Elastic beanstalk环境中工作得很好。很奇怪的是在我的Mac OS上本地的Puma没有问题。但是在64位Amazon Linux 2018.03 v2.11.4运行Ruby 2.6 (Puma)平台上Puma就不能正常工作了。
