应用程序在iOS5模拟器和分析器上崩溃

My app crashes on the iOS 5 iPad simulator after about 5 min of smooth running. This is the only crash reference I get from Xcode, when I try to do a profile run using zombies/memory leak, the app for some reason won't even load (splash-screen shows and then the app crashes), I have no clue what is causing this behavior, any ideas?My app crashes on the iOS 5 iPad simulator afte
