我试图让 uWSGI 刷新它的工作人员，因为他们正在泄漏一些内存。但是，在重新加载工作人员后，它不再响应。我是不是忘记了什么？
uwsgi --http-socket 0.0.0.0:8000 --wsgi-file entry.py --processes 3 --master --req-logger file:/log/reqlog --logger file:/log/errlog --harakiri 15 --max-requests 3
max-requests 3 是测试重新加载：

例如 uWSGI 不再响应（连接永远存在，除非我使用 curl --max-time）。uWSGI 内部如何通信？主进程如何知道如何联系工人？我认为那里出了点问题。
