我运行以发布Celery worker与Rabbitmq的连接在Gevent模式下遇到了管道断裂错误。而当Celery worker在进程池模式下工作时没有问题（没有Gevent，没有猴子补丁）。
之后，Celery工作人员将不再从Rabbitmq获得任务消息，直到重新启动。
当Celery工作者消耗任务消息的速度比Django应用程序生成消息的速度慢时，这个问题总是会发生，并且Rabbitmq中堆积了大约3吨的消息。
Geevent版本1.1.0
西芹3.1.22版

Celery工作者使用eventlet时也会出现类似的问题。

添加安装和负载测试信息
我们使用supervisor启动celery ，并提供以下选项

celery worker -A celerytasks.celery_worker_init -Q default -P gevent -c 1000 --loglevel=info

Celery使用Rabbitmq作为代理。
通过在管理程序配置中指定“numprocs=4”，我们有4个Celery工作进程。
我们使用jmeter来模拟Web访问负载，Django应用程序将产生任务供Celery工作者使用。这些任务基本上需要访问Mysql DB来获取/更新一些数据。
从rabbitmq网站管理页面，任务产生的速度是50/秒，而消耗的速度是20/秒.经过大约1分钟的负载测试，日志文件显示许多连接之间的Rabbitmq和celery 遇到了断管错误
