App Rejection by Apple due to use of watchdog timer for applications in unity3d iOs Game?

I got a rejection from apple due to the following issue.

2.2: Apps that exhibit bugs will be rejected

We found that your app failed to launch on iPhone 4 and iPad 2 running iOS 5,on both Wi-Fi and cellular networks.

We encountered the issue when selecting the application on the Home screen - the app displayed a launch image then quit unexpectedly. This may be because iOS 4 uses a watchdog timer for applications; if an application takes too long to complete its initial startup, the operating 开发者_JAVA百科system terminates the application.

Right now I am confuse. What should I do. Please suggest me the right way.

Hello friends I got the solution. And I had successfully submitted the game on the appstore.

Here I am using a Preloading code for Decrease the Initial Loading time. And I had just put a Blank scene for indicating the application is running. In earlier time it was taken 36 seconds for that. but right now it is 11 seconds for whole levels.

Thanks
