My RPi 3B decided to give up the ghost today or to be more accurate the 16Gb. micro SD card, in 24/7 service running DSLStats, harvesting my 1312B-10A routers stat's..
Initially noticed that DSLStats had locked up although the RPi was still responding to all commands, however, on attempting to re-boot the RPi wouldn't come back to life.
Memory card checked in another RPi and confirmed corrupt / faulty.
Re-programmed another 16 Gb. card, taking the opportunity to upgrade to "stretch", old card had still been running "jessie".
Stored an image of the completed configuration and back in service.
Re-formatted the old memory card and re-loaded full configuration without any errors, currently running this in a spare RPi, not sure if I will trust again for DSLStats service accepting that SD memory cards do have a finite life span.
Not sure of it's age but has been in DSLStats 24/7 service for some considerable time certainly back to MDWS days.
