iPhone App Crashing Upon Close/Reopen

All,

The application I have created w开发者_高级运维orks perfectly the first time around, but if I force close it via the bar at the bottom of the screen and open it back up, it crashes and won't reload. The only error I get is Thread 1: Program received signal: "SIGKILL". and there is nothing in the log. This happens both in the iPhone simulator as well as my physical iPhone.

Edit: I have attached the debug log. Like I mentioned, nothing shows. This is the log AFTER the error is thrown and the application crashes.

Anyone had an issue like this before?

This is expected behavior. If you close your app through the multitasking bar, you need to restart the debugging process over. I've seen this in development several times. This will not negatively impact your app once it has shipped. This happens because the debugger was connected to the app when it terminated. Your users aren't debugging your app so they won't have this issue.
