Hi everyone, 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: CgroupAutomount=yes CgroupReleaseAgentDir="/etc/cgroup" CgroupMountpoint=/sys/fs/cgroup ConstrainCores=yes ConstrainDevices=no ConstrainRAMSpace=yes ConstrainSwapSpace=yes AllowedSwapSpace=0 We are using jobacct_gather/cgroup # ACCOUNTING JobAcctGatherType=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?
