芹菜错误

芹菜的连接“通过对等连接复位”与错误信息定期重置：芹菜错误

[Errno 104] Connection reset by peer

目前，我输了之后触发，直到我重置服务器任务和任何东西。我有两个问题：（1）是什么导致了错误/我该如何防止它？（2）如何在发生错误时重新捕捉错误并重试我的任务？

我在Heroku上运行。 Celery配置了AMQP（CloudAMQP）作为中间件和redis（REDIS_TO_GO）作为后端结果。

堆栈跟踪：

“被连接重置”听起来像是[胡萝卜]（https://github.com/ask/carrot）是给你的麻烦 – dokkaebi

据我了解，胡萝卜一直取而代之的是kombu。 kombu可能导致这个问题？ – Mike

我遇到了非常类似的设置相同的问题。 –

看起来你用完了连接。当你看看CloudAMQP控制台打开连接你可以验证它。

也许看看芹菜BROKER_POOL_LIMIT

设置'BROKER_POOL_LIMIT = None'帮助了我。谢谢。 – Stanislav
