pve kernel: landlock: Disabled but requested by user space. You should enable Landlock at boot time: https://docs.kernel.org/userspace-api/landlock.html#boot-time-configuration
this is a Brand New Build 1 month ago on a R730XD E5-2690 v4 X2 and 64GB of ECC memory
my second Node R730XD E5-2680 v4 X2 and 64GB of ECC memory has been running Proxmox 8 for a year and a half with out any trouble
Reading the docs says may be a VM running alpine Linux as is required but all are Debian or ubuntu based VM's and LXC's
I would be a bit surprised if that informational message has anything to do with the freezes. You can still try to enable landlock as described when you follow the link. Please share the full system journal excerpt from around the time of the issues.
