NUC6CAYH randomly freezes

There are a few threads here on this forum regarding NUC6CAYH becoming unreachable over the network after certain amount of time.

Initially I thought that it's a LAN card issue but then I decided to run a crontab script every 5 minute:

*/5 * * * * ~/just-logging-timestamp.sh >> ~/timestamp.log

So after running the above script it turned out that when the NUC is unreachable over the network, it's in fact frozen, because the timestamp script is not logging anything.

After I restart the NUC from the power wall, I can login again over SSH and I can see that the logs are missing for the time period when the NUC was unreachable.

I'm currently using BIOS 38, and I can upgrade to 41 although I don't see anything related to my issue in the changelog. Obviously even if I update the BIOS it will take some time before I can report back with the results.

Here is the overview of the timestamp script log so far:

- YYYY-MM-DD

- 2017-10-27 - froze

- 2017-10-18 - froze

- 2017-10-02 - manual restart (other reasons)

- 2017-09-30 - manual restart (other reasons)

- 2017-09-24 - froze

- 2017-09-02 - froze

- ????-??-?? - start timestamp script

The NUC is running 24/7 with Debian Stretch, and I can confirm that it's not OS related because I had other Linux OS'es before that and occasionally I had the same issue, although at the time I was thinking that it's a LAN card issue.

Hello simov,

Thank you for joining the Intel® NUC. I am sorry to hear you are having issues with this matter.

Were you able to test BIOS 41? Did the issue persist with this version?

Regards,

Hi, Amy,

Unfortunately no. I'm in the process of moving my projects back to my old Atom based server, then I'll be able to install the latest BIOS and test, but it will take some time to get back to you with results. I'm not seeing anything related in any of the system logs and the NUC continues to freeze from time to time - 10 times in total for the last 3 months.

Thank you for that information Simo.

Please, as soon as you get the chance to test the BIOS let me know.

Regards,

Amy C.
