var db = require('mongodb').db; var connection = require('mongodb').connection; var server = require('mongodb').server; var connectioninstance; module.exports = function(callback) {     if (connectioninstance) {          callback(connectioninstance);         return;     }     var serveroptions = {         'auto_reconnect': true,         'poolsize': 100     };     var db = new db('test', new server('localhost', 27017, serveroptions));     db.open(function(err, databaseconnection) {          if (err)             console.log(err);         connectioninstance = databaseconnection;         console.log("connection established");         callback(databaseconnection);     }); };  //the pgm insert data on mongodb using node.js var = 0; var mongoclient = require('mongodb').mongoclient; var mongoserver = require('mongodb').server; var serveroptions = {     'auto_reconnect': true,     'poolsize': 5 }; var = 0; var async = require('async'); var mongoclient = new mongoclient(new mongoserver('localhost', 27017, serveroptions)); var db = mongoclient.db('test'); var collection = db.collection('new_file_test'); var doc mongoclient.open(function(err, mongoclient) {     if (err) {         console.log(err)     };      function save(callback) {         console.log("am first");         doc = {             'trip_paramid': "111",             'tripid': '116',             'lattitude': '12.8929183',             'longitude': '77.63627',             'speed': '2',             'heading': '0',             'altitude': '80469',             'address': 'qwertyasdfgxcvbn',             'engine_status': 'normal',             'oil_pressure': '83.12',             'water_temp': '28',             'fuel_content': '0',             'brake': 'normal',             'creation_time': '2013-08-31 23:22:17',             'brakelight_status': 'normal',             'battery_status': '12.68',             'event_code': '8',             'dbinsert_time': '2013-08-31 23:24:59',             'gsm_status': '-51',             'cell_id': '45',             'vehicle_id': '123456',             'distance': '0'         }         callback(doc);     }     save(function(doc) {         console.log("i got first");         console.log("inserting" + i);         collection.insert(doc, function(err) {             if (err)                 console.log('error occured');             else                 console.log("inserted" + i);         });     });  });

the problem 32 bit mongodb using can store data of around 2gb. when replaced 64 bit works perfect.
