Virgo Nano shutdown.bat throws error [message #1754068]

Hello,

Whenever we start(startup.bat) the Virgo Nano server, it creates java.exe process. However when we click on shutdown.bat i get the following error.

Java.net.ConnectException: Connection time out: connect.

This error occurs very rarely and doesn't close java.exe process.
Please let me know what are we missing here ?

Are you running multiple instances of Virgo on the same machine?

The script shuts down Virgo by making a remote JMX invocation. If you run multiple Virgo instances on the same machine you will have to relocate the ports for each instance.

This could aso be a firewall problem, e.g. Windows opening the popup asking the user to authorize the process to open the port.

Thanks for the details. Currently i am running single instance of virgo nano. Also i didn't get any windows popup during server start or run.

I was trying to debug the issue. The reproducible steps are as follows,
1. Start the Virgo nano server (startup.bat) when you are at home using company's network (VPN).
2. Come to office, join the office network using office network cable or wifi.
3. Stop the virgo nano server(shutdown.bat)

This will give following error.

The IP address shown above is not valid one in office network(during shutdown of the server). I try to check the shutdownclient.java, but it has 127.0.0.1 as host address.

JMXServiceURL jmxServiceURL = new JMXServiceURL(String.format("service:jmx:rmi:///jndi/rmi://127.0.0.1:%d/jmxrmi", new Object[] { Integer.valueOf(command.getPort()) }));

I am not sure why it tries to connect to unknown IP address and how is it getting the IP address. Could somebody help me on this.

You may have multiple network interfaces, e.g. ethernet, wifi, vpn, virtual machine and maybe the tcpip routing is misconfigured?
Maybe something related to IPv6?

I don't manually configure any network settings. All i have done is connect to different networks and start/stop the Virgo server in different networks. My concern is why it is trying to connect to host IPaddress instead of localhost. Because JMXServiceURL is pointing to 127.0.0.1 and not any IP address.
