clearTimeout and WARNING: Out of memory while appending to array

Hi All,

I am running the following GPS code:

Serial4.setup(9600,{tx:C10,rx:C11});

var SleepDuration = null;
var SearchDuration = null;

function Start_GPS(){
  
  console.log("Starting GPS...");
  //After 120 seconds disable the GPS regardless
  SearchDuration = setTimeout(function (e) { Stop_GPS(); }, 60000);
 
  //Set enable pin mode
  pinMode(A9,'output');
  
  //Set enable pin to high
  digitalWrite(A9,1);
  
  //load gps
    var gps = require("GPS").connect(Serial4, function(data) {
    console.log(data);
    //Check if we have a fix
      if(data.fix>0)
      {
        Stop_GPS();
        console.log("Send SMS:" + data.lat + "|" + data.lon);
      }
  });
}

function Stop_GPS(){
  clearTimeout(SearchDuration);
  digitalWrite(A9,0);
  console.log("Disabling GPS...");
}

function onInit(){
SleepDuration = setTimeout(function (e) {onInit(); }, 120000);
console.log("Starting up device & Setting timers...");
Start_GPS();

}

onInit();

I'm seeing an error popup every so often (not every time the code runs) as shown below:

ERROR: Error processing Serial data handler - removing it.

After leaving the code to execute I am eventually hitting:

"lat":NaN,"lon":NaN,"fix":0,"ERROR: Out of Memory!
satellit":0}

And even later on:

Just wondering if anyone can see whats going wrong here? I assume it might be to do with the setTimeouts and then clearing them?
