clearTimeout and WARNING: Out of memory while appending to array

@Gordon ran the code for a couple of hours and I hit:

{
  "time":"18:54:21",
  "lat":NaN,"lon":NaN,"fix":0,"ERROR: Out of Memory!
satellit":3}
ERROR: Error processing Serial data handler - removing it.
Execution Interrupted during event processing.

{console.log(data);if(data.fix>0){consoin function called from system
Disabling GPS...

Is there any way I can trace where the memory is leaking from?
