Proxmox host reboots at the same time every week.

[Trakker]

I have an issue with one of my Proxmox hosts, it will do a reboot at 17:14 every Sunday.
I can see --reboot-- in the logs, but I have no scheduled tasks setup for it to reboot.

I thought it could have been a hardware issue, but the seemingly weekly schedule for the reboot has totally thrown me.

Has anyone else had this issue?

Hello,

Could you please post here the 2 minutes (or 100 last lines, if 2 minutes contains less lines) before the `-- Reboot` line in the journal? Is this your entire cluster? Just one host? If this is part of a cluster, do you have HA mode enabled in any VM running on this host?

Hi,
Yeah, it's part of a 4 host cluster with 6 VMs running on it but no HA.

the only thing on the logs before it is this
