Original GitHub issue: https://github.com/fatedier/frp/issues/225

frps启动, 先启动一次frpc,连接成功（称呼它为“连接1”）。在连接1成功的状态下，再启动一个frpc进程,配置相同，能不能把上一个连接踢掉，和最新的frpc保持连接。

看一下frps的log:

root@iZ11txj6ya6Z:~/frp/frp_0.9.1_linux_amd64# ./frps -c ./frps.ini
2017/01/12 11:12:52 [main.go:194] [I] Start frps success

2017/01/12 11:19:44 [server.go:429] [W] ProxyName [web02], timeout try
ing to get work connection

这是第二个frpc执行的log:

root@FriendlyARM:~/NanoPi/NanoPiService/modules# ./frpc -c /var/frpc.ini
2017/01/12 03:22:04 [main.go:109] [I] Start frpc success
2017/01/12 03:22:04 [control.go:202] [E] ProxyName [web02], start proxy error, ProxyName [web02], this proxy is already working now
2017/01/12 03:22:04 [control.go:39] [E] ProxyName [web02], connect to server failed!
2017/01/12 03:22:04 [main.go:112] [W] All proxy exit!

看起来第二个frpc客户端直接就退出了

仔细看了一下config.go文件，能不能把406行的return去掉，让他继续执行、？以便让新的frpc客户端取得连接，并且把旧的客户端disconnect掉

在前一个连接还是正常的情况下，后一个连接不会成功，这个是符合预期的。

至于你反馈的前一个连接已经 release 的问题，我会排查一下。

@fatedier 现在是这样的，我用在IoT设备上，设备随时可以断电上电，然后服务端可能还以为client活着，但是客户端上电后再连接就连不上了，所以我希望能够后来的client顶替。然后请你看一下我第二条评论的可行性
P.S. 看了一下，应该前一个连接没有被release

这个问题目前是可以解决的，可以看下我在 #209 这个 issue 中对于重连机制的描述。这样的场景不会有问题，如果想要缩短重连期间的等待时间，可以修改心跳包的间隔时间和超时时间。

@fatedier 但是重点是前一个frpc客户端虽然还连着，也在发心跳包，但是运行不正常，也打不开网页了。

2017/01/12 03:59:48 [control.go:224] [D] Send heartbeat to server
2017/01/12 03:59:48 [control.go:113] [D] ProxyName [web02], receive heartbeat response

2017/01/12 03:59:49 [client.go:169] [D] Join two connections, (l[127.0.0.1:53345] r[127.0.0.1:8888]) (l[172.16.24.119:34482] r[139.196.16)
2017/01/12 03:59:49 [process.go:86] [D] ProxyName [web02], One tunnel stopped

2017/01/12 03:59:50 [process.go:86] [D] ProxyName [web02], One tunnel stopped

然后fprs这样子打印的：

2017/01/12 11:59:15 [control.go:214] [W] ProxyName [web02] is not exist
2017/01/12 11:59:20 [control.go:214] [W] ProxyName [web02] is not exist
2017/01/12 11:59:25 [server.go:429] [W] ProxyName [web02], timeout trying to get work connection
2017/01/12 11:59:30 [server.go:429] [W] ProxyName [web02], timeout trying to get work connection

不知道是什么原因
