芹菜节拍的日志就像这样，最后一行刚刚停止，不再继续并恢复。

它在docker容器中运行。当我通过顶部检查时，它显示出很高的CPU百分比

然后，当我在容器中ssh并尝试执行celery beat命令时。最初返回的以下错误

During handling of the above exception, another exception occurred:

请注意，我只使用纯芹菜而不是django-celery-beat

我亲爱的朋友，当您每次启动Docker容器时，celery要创建celerybeat.pid文件，如果存在，django会对此引发错误。因此，您应该添加以下命令以删除Dockerfile上的当前celerybeat.pid文件，如下所示：

COPY entrypoint.sh /code/entrypoint.sh
ENTRYPOINT ["/code/entrypoint.sh"]
RUN chmod +x /entrypoint.sh

您应该创建一个entrypoint.sh文件，如下所示：

#!/bin/sh
rm -rf /code/badpanty/*.pid
exec "$@"

我希望这会有所帮助。

芹菜跳动因资源错误而立即停止
