[slurm-users] can't create memory group (cgroup)

I'm getting this error lately for everyone's jobs, which results in memory not being constrained via the cgroups plugin.
slurmstepd: error: task/cgroup: unable to add task[pid=21681] to memory cg '(null)'
slurmstepd: error: jobacct_gather/cgroup: unable to instanciate user 3691 memory cgroup
The result is that no uid_ direcotries are created under /sys/fs/cgroup/memory
Here is our cgroup.conf file:
We are using jobacct_gather/cgroup
The partition is configured like this
PartitionName=long Nodes=marzano[05-13] PriorityTier=30 Default=NO MaxTime=5-0 State=UP OverSubscribe=FORCE:1
We are using slurm 16.05.6 on Ubuntu 14.04 LTS
Any ideas how to get cgroups going again?
