title: "GC freed" log in xamarin (it's about memory usage)
body: <p>I need some help.</p>
  
  <p>I am using ffimageloading.
  I have a list of images...with a several number of images.
  In output I can see:</p>
  
  <blockquote>
    <p>Explicit concurrent mark sweep GC freed 23899(1507KB) AllocSpace objects, 43(1032KB) LOS objects, 39% free, 20MB/34MB, paused 154us total 9.754ms</p>
  </blockquote>
  
  <p>then, according I open, close and reopen the lists page, the percentual decreases:</p>
  
  <blockquote>
    <p>Explicit concurrent mark sweep GC freed 19286(1148KB) AllocSpace objects, 41(984KB) LOS objects, 35% free, 29MB/45MB, paused 138us total 13.067ms</p>
  </blockquote>
  
  <p>until 0. When it's zero (about 50 minutes open and closing the lists), the app crashs with out of memory error.</p>
  
  <p>are these logs about RAM memory? What are they about? Should it occures if I am using ffimageloading with cached image? 
  I need to understand this....someone more experient here?</p>
