Gulp-connect is blocking the port, what should I do?

Question

gulp.js

gulp.task('server', function() {
  connect.server({
    port: 5555,
    root: 'build',
    livereload: true
  });
});

After stopping the task in the terminal and subsequent launches, it writes

Error: listen EADDRINUSE :::5555
at Object.exports._errnoException (util.js:855:11)
at exports._exceptionWithHostPort (util.js:878:20)
at Server._listen2 (net.js:1237:14)

Do not constantly change the port
