启动脚本突然appium说超过最大连接数，报错如下

1. ```bash urllib3.exceptions.MaxRetryError:
HTTPConnectionPool(host='127.0.0.1', port=4723): Max retries
exceeded with url: /wd/hub/session (Caused by
NewConnectionError('<urllib3.connection.HTTPConnection object at
0x104646908>: Failed to establish a new connection: [Errno 61]
Connection refused',)) ```

解决方法如下：
将adb服务关闭：adb kill-server
在将adb服务开启 adb start-server
成功啦
如果还不行，排查一下代码，就不是java连接池的问题了
