sgx error (background gpu access not permitted)

I recently started seeing this error in my Cocos 2d iPhone application running on iOS 4.1:

sgx error (background gpu access not permitted):
Program received signal: “SIGABRT”.

After searching around, I found this thread on the cocos2d forum.

I modified my code in the ApplicationDelegate to look like:

- (void)applicationDidEnterBackground:(UIApplication *)application
{
	[[CCDirector sharedDirector] stopAnimation];
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
	[[CCDirector sharedDirector] startAnimation];
}

- (void)applicationWillResignActive:(UIApplication *)application
{
	[[CCDirector sharedDirector] pause];
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
	[[CCDirector sharedDirector] resume];
}

This solved my problem. I hope it helps someone else.
