did you manage to find a solution to this without disabling cgroups v1?

In our case:

| slurm 23.02.3
| Ubuntu 22.04.3 LTS
| # cat /proc/cmdline 
| BOOT_IMAGE=/boot/vmlinuz-5.15.0-83-generic root=UUID=... ro quiet splash cgroup_no_v1=all vt.handoff=7

disabling cgroups v1 has been working reliably, but it would be nice to
find a solution that doesn't require modifying the kernel parameters.
