simple getJSON code and memory loss

simple getJSON code and memory loss

Below is some simple code asking for json data from flickr periodically. I see it causing increasing  memory consumption over time. I even tried a simple json string (from a local server) and it keeps on increasing the memory consumption (so its not probably the json string thats causing it). I checked it via chrome's developer tools and with each call to the server, the increase is proportional. Is there any way to stem the increase in memory leakage.

I am a beginner js so i might be totally wrong on whats causing this. Any help is greatly appreciated.

  3. $(document).ready(function(){
  4.     updateScreen();
  5. }
  6.    );

  8. function parseJSON( data){
  10. }
  11.  
  12.  function updateScreen(){
  13. setTimeout('updateScreen()',1000);
  15. $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", parseJSON);
  17. }
