The problem is that if you don't handle this error and keep the server alive, this remote crash exploit could be used for a DOS attack. However, you can handle it and continue on, and still shut down the process when unhandled exceptions occur (which prevents you from running in undefined state -- a very bad thing).

The connect module handles the error and calls next(), sending back an object with the message body and status = 400. In your server code, you can add this after express.bodyParser():

var exit = function exit() {
  setTimeout(function () {
    process.exit(1);
  }, 0);
};

app.use(function (error, req, res, next) {
  if (error.status === 400) {
    log.info(error.body);
    return res.send(400);
  }

  log.error(error);
  exit();
});
