Silly me, I'm not up to speed on proper error handling in node. Fixing postOut() did the trick:

function postOut(dataToPost){

    var querystring = require('querystring');
    var http = require('http');

    var post_domain = 'localhost';
    var post_port = 8081;
    var post_path = '/';

    var post_data = querystring.stringify(dataToPost);

    var post_options = {
      host: post_domain,
      port: post_port,
      path: post_path,
      method: 'POST',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': post_data.length
      }
    };

    var post_req = http.request(post_options, function(res) {
      res.setEncoding('utf8');
      res.on('data', function (chunk) {
        console.log('Response: ' + chunk);
      });
    });

    // Handle various issues
    post_req.on('error', function(error) { // <-------------------------------- Yeah Buddy!!!
        console.log('ERROR' + error.message);
        // If you need to go on even if there is an error add below line
        //getSomething(i + 1);
    });
    post_req.on("response", function (response) {
        console.log(response);
    });

    // write parameters to post body
    post_req.write(post_data);
    post_req.end();
    request.on("response", function (response) {
        console.log(response);
    });
}
