Catching an uncaughtException in express.js based server

my_server.js

var express = require('express');
process.on('uncaughtException', function(err) { 
    console.log( " UNCAUGHT EXCEPTION " );
    console.log( "[Inside 'uncaughtException' event] " + err.stack || err.message );
});

anHTTPServer = express.createServer(function (req,res){
  if (Math.random() > 0.9) throw new Error('fail!');
    res.send("Hello World : Express!!");
});

anHTTPServer.listen(3000);

You have a problem with this approach. Basically, is a exception occurs and you catch this on your proccess.on you will perform the callback to any other requests.
