python - Celery worker - ConnectionResetError: [WinError 10054] 现有连接被远程主机强行关闭

问题描述

执行长时间运行的任务时，Celery 连接中断。我使用 amqp 作为代理，使用 redis 作为后端。

Celery 在远程主机上运行，​​我用于 celery worker 的命令如下

pipenv run celery worker -A src.celery_app -l info -P gevent --without-mingle --without-heartbeat --without-gossip -Q queue1 -n worker1

错误日志如下：-

[2020-09-09 14:26:46,820: CRITICAL/MainProcess] Couldn't ack 1, reason:ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None)

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

无法理解为什么会发生此错误。
