Finally found solution just try this code. Its maintain sticky as well as it uses all the cpus [ process ] for other clients. You can use express cluster sticky session using following code. You can get sticky-session here https://github.com/indutny/sticky-session

var http = require('http');
var cluster = require('cluster'); // Only required if you want the worker id
var sticky = require('sticky-session');
var express = require('express');
var app = express();

app.get('/', function (req, res) {
    console.log('worker: ' + cluster.worker.id);
    res.send('Hello World!');
});


var server = http.createServer(app);
    sticky.listen(server,3000);

It has nothing to do with Express.

You just forgot the listen() on the sticky function.

sticky(
  http.createServer(app).listen(app.get('port'), function () {
      console.log('Express server listening on port ' + app.get('port'));
  });
).listen(app.get('port'),function() {
  console.log('Sticky server started on port' + app.get('port'));
});
