Hi @Ziang,

I understand that you are facing an issue with starting the MATLAB Production Server dashboard, where you are encountering an error related to a busy or locked resource and a PostgreSQL connection issue.

This is happening because the PostgreSQL server might be running multiple processes in the background, or the port that PostgreSQL is attempting to use is already occupied by another service.

To fix this, you can try the following steps:

1. Terminate Background Processes:

- Open the Task Manager on your Windows machine.

- Look for any PostgreSQL processes that are running in the background and terminate them.

2. Check for Port Conflicts:

- Run the command `netstat -b` in the Command Prompt with administrative privileges to identify if any other process is using the same port as PostgreSQL.

3. Change the Database Port:

- Open the `config.txt` file located in your MATLAB Production Server installation directory.

- Find the line with `--databasePort 9080` and change `9080` to another available port number.

- Save the changes and restart the setup.

This will make sure the database will be setup at the new port configured.

Hope it helps!
