Had this message on my router - all other PIX etc equipment has remained up 1 year + This router is internet facing and performs NAT and failover.

Error

Internet-GW uptime is 1 week, 1 day, 5 hours, 29 minutes

System returned to ROM by address error at PC 0x18, address 0x18 at 11:30:05 PCTime Sat

System image file is "flash:c180x-advipservicesk9-mz.124-2.XA.bin"

Any ideas what could have caused this and how can I find additional debug inormation?

Thanks
