The file containing system persistent data cannot be found and auto-recovery backup of the previous last-good system state is not available. In normal circumstances system state is automatically stored to persistent memory during shutdown and an auto-recovery copy of previous last-good state is preserved. System configuration and RAPID programs are lost and will have to be re-implemented or reloaded from a user stored backup.
