Digi One IAP losing it's configuration?

I use many Digi One IAP’s to connect to Allen Bradley SLC PLC’s via Ethernet. I have one that keeps losing it’s configuration, specifically the Industrial Automation settings. Does not lose it’s network settings. I restore the configurations and reboot and it will work fine for awhile, but it’s happened twice now. What would cause this and how do I fix?

Thanks,
Ted
