Are you checking the crash logs on the device itself? (Ctrl+Cmd+O in Xcode from memory.)

Also, are you doing large amounts of processing on start-up? (I know that iOS will terminate applications that don't finishing launching within a certain time period.)

Irrespective, without more information on the specific error, there's not a lot else to suggest.

If you start with the debugger, you can check the console after the crash for what crashed!
