ios - Cocos2d and iPhone: Parallax Background with multiple texture atlases gives many memory warnings

The problem I am trying to solve is:

I have 6 stripes which I need to move at different speed. A texture sheet of 2048*2048 is not enough and to deal with this I splitted the image in two (top and bottom half), so each stripe is exactly 960*640pixels. The general algorithm is to allocate a top and bottom half for each stripe and move them at each frame making sure to reposition them at the top of the screen when they exit the user's view. My class implementation, a direct modification of ParallaxBackground in the ShootEmUp example from this book, is giving too many memory warnings when run and analyzed using Instruments. See analysis below:

OpenGL analysis: OpenGL analysis

Activity monitor: Activity Monitor analysis

What concerns me is the high number of memory warnings in both analysis (24 and 5 respectively).

EDIT: Below you can find a comment which explains the solution

2048x2048 is maximum possible size of texture for new devices. you can read about it in Apple OpenGL ES Programming Guide
