after some months of flawless activity, the ethernet connection of a RevPi Core 1 crashed, the attached DIO, DI modules kept working but the revpi was not reachable any more. Unplugging and plugging back the ethernet cable did not help, I had to switch it off and once back the ethernet was running OK.
Being installed in a remote wiring closet the web connection reliability is crucial.
Below the details of the system and attached the kernel logs.
Operating system: Raspbian GNU/Linux 8.0 (jessie)
Code: Select all
uname -a
Linux RevPi100102 4.4.50-rt66+ #1 PREEMPT RT Wed, 20 Sep 2017 07:09:15 +0200 armv6l GNU/Linux
cat /etc/revpi/image-release

It happened around Aug 26 12:43, the logs lines contain all the related errors.
Could you please analyze them and let me know if it is a problem and if there is a solution?
Thank you
Enrico
PS: I noticed these lines in the daemon.log
