Unexplained system reboot - Any advice?

[HarambeLives]

My secondary NAS which is actually a VM inside of ESXi just rebooted for no reason. No other issues with the ESXi host, all VM's stable and nothing else rebooted

I checked /var/log/messages and this is what I see

Has anyone else encountered a similar issue? I'm on 12.0 U8

I'm going to upgrade to 12.0 U8.1 and see if it happens again. Uptime before this was perfect, no reboots since I upgraded to U8 when it was released
