slackclient OSError：[Errno 24]打开的文件太多

时间：2018-12-06 16:56:03

标签： python linux slack urllib3 eoserror

我在我的应用程序上添加了slackclient以获得常规通知。 该应用程序在AWS Linux和docker容器（FROM python：3.6.6-stretch）中执行。

每当我尝试执行约1000次循环，但过程失败  刚循环1000次后，出现以下错误。

我已经检查了stackoverflow上的其他情况，但对我来说不起作用。希望我能从您的回答中得到一些启示。我个人想知道为什么会这样并解决核心问题，而不仅仅是绕路。
