Question

即使超时后，独角兽似乎也不会杀死并重生工人。

这是我的代码（ myapp.py ）：

 def app(environ, start_response):
 data = b"Hello, World!\n"
 start_response("200 OK", [
     ("Content-Type", "text/plain"),
     ("Content-Length", str(len(data)))
 ])
 return iter([data])

这是我触发Gunicorn服务器的方式：

gunicorn -t 10 -w 1 --log-level debug myapp:app

这是日志：

您可以看到超时设置为10秒，但是即使在闲置5分钟之后，该工作人员也从未回收。

我在这里想念什么？非常感谢在这方面的任何帮助！

好吧...只是想通了。 [1]上的官方文档说：

沉默了许多秒的工人被杀死并重新启动。

在这里，silent这个词让我感到困惑。我以为GUnicorn可以回收工人在timeout表示的一段时间内闲置的东西。实际上，它实际上杀死了收到请求但在timeout参数所提供的时间段内未完成的工作人员。

我认为non-responding比silent更好。

枪支即使超时也不会杀死工人
