"listen" in "http" produces error [arm]

[am-trouzine]

I tried a simple http server example:

var http = require('http');
function fn(eq, res){
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write(req.url);
  res.end();
}
var server=http.createServer(fn);
server.listen(8000);

It gives the error:

events.js:163
      throw er; // Unhandled 'error' event
      ^

Error: listen EFAULT :::8000
    at Object.exports._errnoException (util.js:1034:11)
    at exports._exceptionWithHostPort (util.js:1057:20)
    at Server._listen2 (net.js:1265:14)
    at listen (net.js:1301:10)
    at Server.listen (net.js:1392:7)
    at Object.<anonymous> (/storage/sdcard0/shell/bin/nodejsServer.js:8:8)
    at Module._compile (module.js:571:32)

    at Module.load (module.js:488:32)
    at tryModuleLoad (module.js:447:12)

Adding the second parameter to liste, also produces an error:

    at exports._exceptionWithHostPort (util.js:1057:20)
