Port being already in use is not handled well #26

Open Aruee opened 8 years ago

Aruee commented 8 years ago

Starting a second instance of cobra does not use the next available port or at least handles the error nicely but instead shows an exception stacktrace on the console and seems to just crash the application:

    $ cobra 
            ____      _                     
           / ___|___ | |__  _ __ __ _ TM    
          | |   / _ \| '_ \| '__/ _` |      
          | |__| (_) | |_) | | | (_| |      
           \____\___/|_.__/|_|  \__,_|
