Answer 1

You might have some broken privileges or a hung debugger process (one that didn't quite exit fast enough). Restart Xcode or restart your phone, either way, it's not as bad as it's more annoying cousin, Processes That Can't Be Registered To The BootStrap Server

If all else fails, restore it from a backup.
