【问题描述】：
gunicorn 似乎在超时后也不会杀死并重新生成工人。
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：

如您所见，超时设置为 10 秒，但即使经过 5 分钟的空闲期，worker 也从未回收过。
我在这里缺少什么？非常感谢您在这方面的任何帮助！
【问题讨论】：
-
你确定那个工人没有默默地回收吗？您能否验证该过程在
10秒后没有更改其PID？ -
另外，您能否澄清一下
--log-level存在于您的gunicorn版本中？至少我只有--log-syslog或--logger-class STRING。另外，尝试使用--spew键运行gunicorn。 -
嗯...附加的日志显示所有 PID 为
20972。 -
是的，
--log-level确实存在于我的独角兽中。让我试试--spew选项。
