title: app closes due to memory issue
body: <p>My app closes itself during syncing process whenever it has to download lots of images.  </p>
  
  <p>It works perfectly fine with emulator, but when I run it on device it closes after downloading few images with "terminated due to memory issue" warning in console.</p>
  
  <p>If I reduce the number of images to download, it work fine on device.</p>
  
  <p>Any suggestions?</p>
