Since 11.2 upgrade, server reboots suddenly

[fred2018]

Hi,

I've migrated a PowerEdge Server (acting as a storage for ESXi VM) from 11.1U5 to 11.2 version and since then, this server has sudden reboots : it happens 1 or 2 times a day and never at the same time.
I can't find anything in /var/crash and log files don't seem to contain something useful.
Is there any option I could activate to help troubleshooting ?

Thanks in advance for your help.

Hi, we've reinstalled the whole server (which has been continuously upgraded since 2015) and also updated the SSD firmware last week.
Since then, everything seems fine. As this sudden reboot happened multiple times a day, I think the problem is solved.

Sadly, I was too confident. The system rebooted two times since yesterday.
I will create a report at bugs.freenas.org.
