Celery 3.0.1 中的框架错误

问题描述

我最近从 2.3.0 升级到 Celery 3.0.1，所有任务都运行良好.很遗憾.我经常收到框架错误"异常.我也在运行主管来重新启动线程，但由于这些线程从未真正被杀死，主管无法知道需要重新启动芹菜.有人见过这个吗?

I recently upgraded to Celery 3.0.1 from 2.3.0 and all the tasks run fine. Unfortunately. I'm getting a "Framing Error" exception pretty frequently. I'm also running supervisor to restart the threads but since these are never really killed supervisor has no way of knowing that celery needs to be restarted. Has anyone seen this before?

推荐答案

虽然我不确定为什么会发生这种情况，但从 amqplib 切换到 librabbitmq 帮助我克服了这个麻烦.

While I am not sure why this actually happens, switching from amqplib to librabbitmq helped me to overcome this trouble.

我没有更改任何配置，只是:

I haven't changed anything in configuration, just:

pip uninstall amqplib
pip install librabbitmq

并重新启动芹菜工人.
