GL_STACK_OVERFLOW (0x503) error Cocos2d - memory-management

Question

So I have it set up so when the characters health is < 100 (for testing purposes) it stop the scene and goes to the game over scene.
if (playerDataManager.playerHealth < 100) {
[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:3 scene: [GameLogic scene]]];
}
However when the players health drops below 100, it goes to the new scene, but the FPS drops dramatically from 60 to 5.
I get a list of OpenGL error 0x0503 in -[EAGLView swapBuffers] then it stays frozen like that for about 40 seconds, then the FPS unfreeze and goes back out to 60 and I get a list of 2012-07-13 10:37:50.234 Tilegame[93513:10a03] cocos2d: removeChildByTag: child not found!
Then I can continue with the app like normal, going back to the main menu, starting a new game, then recreate the error.

Answer 1

OpenGL error 0x503 means GL_STACK_OVERFLOW, it means you are pushing too many things onto the opengl stack.
I see several instances of pushScene in your code, but no instances of pop anything anywhere. You cannot just keep pushing things indefinitely without popping them, or you will get this error.

Answer 2

We need to what is currently running in your scene, how it has been allocated and how it is released. We also need to know the same information for the new loaded scene GameLogic. Edit your question and add these data.
