Proxmox reboots when doing certain write task

[emotionalburro]

Fresh pve9 install on new nvmes. After restoring lxcs and vm from pve8 things ran for a few days. At some point the system would reboot itself.

2 nvmes: ext4 boot, zfs secondary

From troubleshooting, there seem to be no logs at the time of the actual reboot, the lxc which is wireguard from helper script with qbit triggers reboot on downloading ISO. Trying to creating an lxc also triggers reboot.

journalctl -p err -xer shows
