Out of memory while appending to array!!!!

Hi Gordon,
in this project we are trying transmit GPS data on "NRF"... this is the script which i am using.

var data=command.test();
var arr = [];
data+=command.gps();

eval(data);
eval(Modvar.nrf());
Serial2.setup(9600);
Serial5.setup(9600);
Serial5.on('data', function (data) { print(+data); });
function onInit(){nrf.init([0,0,0,0,2],[0,0,0,0,1]);}
onInit();
setInterval(function() {
  nrf.masterHandler();
//  print(process.memory());
}, 50);

function nrf_print(data){

 // var i =nrf.sendString("\n"+data);
  print("result :"+data);
   
}


//eval(command.gps());

var gps =ConnectGps(Serial2, function(data) {

   if(data.tag == "GGA")
   {
     console.log("\r\n lat:" +data.lat);
     console.log("\r\n lon:" +data.lon);
     console.log("\r\n fix:" +data.fix); 

     // lat
     arr[6] =  parseInt(data.lat[0],10)*10 +  parseInt(data.lat[1],10);
     arr[7] =  parseInt(data.lat[3],10)*10 +  parseInt(data.lat[4],10);
     arr[8] =  parseInt(data.lat[5],10)*10 +  parseInt(data.lat[6],10);

     // lon
     arr[9] =  parseInt(data.lon[0],10)*10 +  parseInt(data.lon[1],10);
     arr[10] =  parseInt(data.lon[3],10)*10 +  parseInt(data.lon[4],10);
     arr[11] =  parseInt(data.lon[5],10)*10 +  parseInt(data.lon[6],10);
   }


 else if(data.tag == "RMC")
  {

    console.log("\r\n time:" +data.time);
    console.log("\r\n date:" +data.date);
    console.log("\r\n speed:" +data.speed);
	console.log("\r\n valid:" +data.valid);
	console.log("\r\n course:" +data.course);

    // time  
    arr[0] =  parseInt(data.time[0],10)*10 +  parseInt(data.time[1],10);
    arr[1] =  parseInt(data.time[3],10)*10 +  parseInt(data.time[4],10);
    arr[2] =  parseInt(data.time[7],10)*10 +  parseInt(data.time[8],10);

    // date
    arr[3] =  parseInt(data.date[0],10)*10 +  parseInt(data.date[1],10);
    arr[4] =  parseInt(data.date[3],10)*10 +  parseInt(data.date[4],10);
    arr[5] =  parseInt(data.date[7],10)*10 +  parseInt(data.date[8],10);

    // valid
    arr[12] = data.valid[0];

    // speed 
    arr[13] = parseInt(data.speed,10);
    nrf_print(arr);
  }
   
});

in this

nrf_print(arr);

if i changed this one to static data like nrf_print("Helloworld"); there is no problem with memory... i think this "arr "array is creating some problem...

Thanks
