We’re seeing it happen on both bare metal and virtual machines.

The VMs are libvirt/QEMU/KVM managed by OpenNebula. The hypervisor is running AlmaLinux 8 with the 4.18.0-477.15.1.el8_8.x86_64 kernel. The VMs have 2 physical/8 vCPUs allocated to them. The VM I used for the reproduction has 2GB of RAM. The VMs where we saw the problem initially have 22GB, but the setup there is a bit more complicated - there are various cgroup v1 limits, such as 2.5GB for system.slice, and 2GB for user slice. However none of that is necessary to reproduce the issue.

Since the initial report, we've done a lot of test runs with INFO-level logging on 20.04, 18.04, 22.04, as well as RedHat-family distributions, and we haven’t seen the issue again. Could be some memory corruption bug that is present only on 20.04, I guess.

So far I’ve been unable to reproduce it on a 22.04 VM with DEBUG logging on.

Thanks.
