Hello everyone,
I am hitting a strange memory problem with box2d on the device and not on the simulator. And i thought how do we ensure that once our game starts that there is enough memory for it to run? Is there any way of specifying some kind of minimum requirement?
thanks

Your app is probably receiving low memory warnings, they should be in the console logs. When Cocos2D receives memory warning it calls [[CCDirector sharedDirectod] purgeCache] which isn't very save.
You can remove this call in AppDelegate:
- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application
My previous apps crashed a lot on devices with multitasking, because Cocos2D was purging data even on loading scenes. Memory warnings on iOS are just useless. I think those calls should be only called when there's really no memory left, but they are called everytime iOS decides to kill backgrounded app.
If your app is in the foreground iOS will try its best to end the background apps that need much memory by sending memory warnings to them, compressing their memory usage and stopping them if necessary. So you'll have the memory you need - but don't exaggerate your usage! In the background however your app can be killed by iOS at any time.
