Kernel messages dump_header, page_fault, Bad RIP value

I have a Proxmox 6 cluster on ZFS Mirror (pve-manager/6.0-5/f8a710d7 (running kernel: 5.0.18-1-pve)

I run 31 LXC with 1.75 GB assigned (54 GB) on host with 96GB.

free -h
              total        used        free      shared  buff/cache   available
Mem:           94Gi        73Gi         9Gi       1.2Gi        11Gi        21Gi

The LXC are not showing low memory in GUI.

In syslog I find:

kernel: [1234333.445570] Code: Bad RIP value.

Any suggestion on how to troubleshoot these issues?

Thank you
Please attach the complete log as a file here. Also the output of 'pveversion -v'.

So, all the 'Bad RIP value' call traces are from containers? What's running in there?
Did you run a memtest already?
