Describe the request

From @kittaakos comment

Besides the application-level error handling for the services, I would like to get a proper exit code and a terminating daemon process when something went wrong. Now, IDE2 must sniff into the stderr of the process, parse such messages and kill the daemon process because it's not terminating, although the daemon is nonfunctional:

• To determine a Failed to listen on TCP port. Address already in use. error message:
  failed to listen, address already in use, bind, only one usage of each socket address

• For invalid address: Failed to listen on TCP port. Unknown address.:
  is unknown name or tcp/ and is an invalid port

• To provide the Failed to listen on TCP port. Invalid port. to the user:
  is an invalid port and failed to serve
