python-2.7 - 无法收听错误 : Couldn't listen on any:9008: [Errno 98] Address already in use

Question

我正在通过 python 在 websocket 上开发 Autobahn 的应用程序。我发现一个问题，如果我在中断后重新启动我的服务器代码一次，那么我的服务器代码将向我发送如下错误:

2016-03-03 13:20:34+0530 [-] Log opened.
2016-03-03 13:20:34+0530 [-] Traceback (most recent call last):

2016-03-03 13:20:34+0530 [-]     raise CannotListenError(self.interface, self.port, le)
2016-03-03 13:20:34+0530 [-] twisted.internet.error.CannotListenError: Couldn't listen on any:9008: [Errno 98] Address already in use.

我错误地理解有一些基本服务即使在中断服务器后仍在运行，但是所有这些端口有多清晰？

Answer 1

sudo lsof -i TCP:9008 | grep LISTEN 效果很好。
