Hello,
I have been having similar issues but failed to get the syslog before hard rebooting (no other method to reboot, just sits at command line not doing anything). I do remember seeing the "PREEMPT SMP" message though in the syslog at some point (idiotic that i didn't save it before power cycling). I have also been using unraid successfully for a number of years without issue. Since moving to 6.x a month or so ago I have had multiple crashes, once about every week or 1.5 weeks. Last was Dec 3rd, then again today.
I was a little hesitant in upgrading to 6.x as I really prefer my file server be simply be a file server and do one and one thing really well, which unraid has for years. I upgraded anyway with absolutely no intention of using docker or any of the virtual machine stuff as I have a separate xen server for that.
FYI, server is on UPS and has no power issues.
Anyone have any thoughts on the crashes? Sanchez have you figured anything out or resolved the issue?
Thanks
