It’s backing up every 4 days and keep 8 backups. Currently there are 2 with build 555 available. To rule out if 571 ist the reason for my ROON problem, I try the latest 555 and will let you know what happens.
After the restore it was still 571. Don’t know if it is updating itself to the latest version after the restore. And it’s still restarting the server.
So I tried your suggestions but didn’t restore a database to have a fresh one. Still restarting.
If the reboots are still occurring after a fresh database, this could be a hardware or operating system issue. I would suggest starting off with the operating system reinstall, you can do this via the ROCK WebUI:
@Dieter_Achenbach - If the reinstall does not help, I would try reinstalling ROCK from a USB stick.
If the issue is still the same after that, checking the RAM with Memtest86 and checking the SSD/using another SSD would be my next suggestion.
Thanks for sending the new logs over and appreciate your patience until I had a chance to review. I do see the RoonServer restarts, but as for the reason as to why they occur, is not clear yet.
In the logs you sent, it appears that ROCK has been restarting since the oldest log, which was a few hours ago before your saved them.
I suspect this might end up being a hardware issue, have you tried hosting Roon on a different SSD? I would also check the RAM on the NUC, perhaps there’s a bad RAM stick that causes the system to fail, I would run Memtest x86 (free version should be ok) to check for RAM errors.
