帮忙解决了的话，报我支付宝，我给你转钱（ 50 ）

用 java -jar arthas-boot PID 来进入，


报错信息如下：

后面去社区查了下，发现说用 as.sh 来启动看看。

然后用 as.sh 选第一个 10434 是可以进入的，但是选择第二个 10323 缺不行了。一样报的
java.net.ConnectException: Connection refused (Connection refused)

[root@cnncc arthas]# ./as.sh

https://github.com/alibaba/arthas/issues/2169 issue 说是防火墙问题，请注意

[imzcg2]

https://github.com/alibaba/arthas/issues/2255 这个也有可能，需要注意

[gweipingzhang]

@imzcg2 我是能启动成功过的，如果是防火墙的问题，那通过 as.sh 去选进程的时候，就不应该成功。但是我是成功了的。

[imzcg2]

https://arthas.aliyun.com/doc/faq.html#target-process-not-responding-or-hotspot-vm-not-loaded 这里的也请去注意一下

有没有可能是启动了 10434 之后端口占用了， 进入 10434 之后 stop 再进 10323 看看？
