  @mehmetuysal thank you for your reply,
  @john26 it seems these are Gideros related bugs.
  Fixing these type of errors in new Gideros versions would be my preference over the new feature addition.

  From the most common to less common error,
  http://crashes.to/s/b826bb9f68f (This one occurs only on iPads, and the remaining memory is usually low)
  
  http://crashes.to/s/97875a95379 ( This one occurs only on devices with ios8, %90 iPad, %10 iPhone)
  
  http://crashes.to/s/21fed7eee7a (only at ios8 devices)
  
  http://crashes.to/s/f66afa9bb97 (Seems to be Ads plugin related,)
  
  Possible memory leak locations according to XCode memory profiling tool

  I can share the exported memory profiling doc, if anyone interested.
  
  The memory usage by the application goes around 130MB

  Ok, first one is related to graphics and the problem is it crashes in driver (IMGSGX543GLDriver)
  While performing rendering
  glrSGXRenderVertexArray + 1156
  glDrawElements_ACC_ES2Exec + 382
  glDrawElements + 38
  GraphicsBase::draw(ShaderProgram*, VertexBuffer*) (graphicsbase.cpp:36)
  Sprite::draw(Matrix4 const&, float, float, float, float) (sprite.cpp:230)
  Application::renderScene(int) (application.cpp:336)
  
  Maybe @john26 or @hgy29 would know better what is going on in there, but this could be the issue:
  http://discuss.cocos2d-x.org/t/engine-crash-on-ios7/9129/6
  
  
  About 2) and 3) they are definitely UrlLoader related. Something is nil when it is attempted to release it, or because of auto release.
  
  4) It is Ads which crashes on app exit, again when trying to release if something is already release:
  https://github.com/gideros/gideros/blob/master/plugins/ads/source/iOS/Plugins/Ads/AdsStateChangeListener.m#L24
  
  All in all, my guess is, is it possible that you have auto release setting enabled (or what was it called ARC ?) on all Gideros libraries and plugins and thus you have this issue, because Gideros cleans its own mess and ARC attempts to clean it too?
  
  If that is not it, then those are bugs in Gideros

  @ar2rsawseen Thank You, For the Analysis,
  Regarding autorelease , Not sure what it is,
  I am using the exported iOS project,
  And I am not adding autorelease, tags.
  When I searched the project I have encountered with some autorelase tags but these are the defaults coming from an ios export over Gideros.
  
  I have did some performance tests by disabling the ads, The memory usage is decreased by half. (i.e from 120 MB to 60MB)

  For 2) and 3°, if it is UrlLoader based then there is a possibility that it could be the same bug that was recently found (and fixed in next release) for Android UrlLoader.
