[Need Help] Unscheduled Reboot for 3 consecutive days

[nonjtjt]

Hello, my freenas has alert mail to me every day since 27-June

* mynasname.local had an unscheduled system reboot.
The operating system successfully came back online at .....

here is the copy of "/data/crash/info.0 info.1 info.2" file

How is the cooling of the system? Havnig the reboots around the same time could suggest you're putting a lot of load on the system at that time (maybe cron) and generating a lot of heat causing a crash.

Another possibility is bad RAM, which a memtest can help you with - but my first idea is still cpu/cooling.
