ruby-on-rails - 为什么 MailChimp 会出现间歇性 Excon::Errors::SocketError: EOFError (EOFError) 错误？

Question

从 Rails 控制台使用 MailChimp gem 时出现间歇性错误。

这是错误:

Excon::Errors::SocketError: EOFError (EOFError)

Answer 1

我在 Excon::Errors::SocketError: EOFError (EOFError) 上做了一些搜索，发现了 this carrierwave issue ，这似乎符合我的经验。

我能够重现此行为 - 如果我让我的控制台在那里坐一会儿，然后调用 MailChimp 的 API，它会失败一次并出现上述错误。如果我重试相同的调用，它会成功。

所以这个问题似乎是由于让套接字打开超过了保持事件的值。不幸的是，我不知道除了“不要那样做”之外的修复/解决方法。
