我在docker上的centos7上运行airflow 1.8，但我的网络服务器未连接到浏览器。我通过pip2.7安装了气流。Flower ui正常运行，使用CeleryExecutor在ECS上运行，initdb运行到与postgres和redis后端的连接，并且我以root身份运行。通过气流Web服务器将Web服务器部署到默认8080。
根据以下显示的日志，是否有人知道导致枪杀工人离开的原因/解决方案是什么？具体来说，好像是这条线
ERROR - [0 / 0] some workers seem to have died and gunicorndid not restart them as expected
