Using to verify that the hostname and OS selected port number are eventually determined correctly. However, as i_imp() may be called many times throughout the lifetime of a flowgraph, this can't be the final place where the endpoint is generated. It appears that the initial calls within the first few milliseconds of TServerSocket creation may return an incorrect port number when getPort() is queried (i.e. 0 if a randomly open / selected port is requested vs. the selected port number). Endpoint string generation and the call to the logger should probably be moved to a function that executes only once after the results from getPort() have had time to settle.
