wait_fences: failed to receive reply: 10004003 while displaying UIAlertView and home button pressed

I have searched the forums regarding this and found no information on this error. I created a simple single view application in xcode and added code to create a test alert in viewDidLoad method.

- (void)viewDidLoad
{
 [super viewDidLoad];

  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert Test"
                                        message:@"Alert Test"
                                       delegate:self
                              cancelButtonTitle:@"Dismiss"
                              otherButtonTitles:nil];
  [alert show];
// Do any additional setup after loading the view, typically from a nib.
}

I have not added any other code. When I run this on my iphone 4 it runs without any problem. But when I click the home button of my iphone 4 with the alert displayed I get the mentioned error.

Device: iphone 4 OS: iOS 5.1.1

Please help. Thanks in advance

you should not display the alertView in viewDidLoad, [UIAlertView show] displays the alertView using animation. we should avoid animation performance when we are not in screen/view , display the alertView in viewDidAppear instead.

EDIT:

-(void)viewDidLoad
{
  [super viewDidLoad];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(dismiss) name:@"UIApplicationWillResignActiveNotification" object:nil];
}

-(void)viewDidAppear:(BOOL)animated{
 [super viewDidAppear:animated];
alert = [[UIAlertView alloc]initWithTitle:@"test" message:@"test" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
[alert show];
}

//do not forget to add this in your header
-(void)dismiss{
   [alert dismissWithClickedButtonIndex:-1 animated:NO];
 }
