UnRaid unexpected restart

Dear all

 

I need your help, I think (my feeling only) that my unRaid started to restart at random intervals, 3-5-7-10 days and this started to happen after update to v6.8, is it possible?

 

I have not touched machine configuration at all.

 

obviously there could be problem with hardware but it is hard to believe that the only symptom of hardware failure to be random restart.

 

How should I diagnose?

 

Last reboot was 1 hour ago and it looks as clean restart as machine did not start to check parity after reboot.

 

Many thanks for your kind help

I switched reporting of logs to syslog server to keep them all and I noticed that there is big number of errors saying CIFS VFS: Close unmatched open. Can this be a problem leading to restarts?

 

Thanks
