Not sure why but my original post just disappeared...let's try this again...

I have two Proxmox hosts in two separate clusters that with similar issues, though one is for sure having a rougher time than the other one as it hard freezes a lot more often. Both are running different hardware (brands of servers and models of CPUs, RAM, etc)

Below is the biggest problem child:

As you can see there are more than enough resources and at most I've only had a handful of VMs on here (maybe 3-5 at a time) given the issues. Sometimes it works fine for days other times it crashes multiple times a day. I say crash, but I should say hard freeze. It is accessible via IPMI/iKVM/iDRAC so at least I can reset it remotely. What's odd is memtest comes back clean and no issues. These used to run Hyper-V and never had issues and ran for months at a time without incident. Logs don't seem to show anything since the server just hard freezes. Any thoughts?

If you look at the logs related to the previous boot (before the reset)
journalctl -b -1
Do you spot some useful message?
