Launch image re-appear after hitting the "Home" button and reopening the app several consecutive times

Programming for iPhone: Launch image re-appear after hitting the "Home" button and reopening the app several consecutive times on newest questions tagged iphone – Stack Overflow

If I press the home button and then re-launch the app, after around 10 times, the application showing splash screen and stuck for a few seconds or even crash.
There’s a reason that could happen?

(The app is configured to background)
