Hello Vladimir, thank you for your response.

this is the cgroups.conf file:

ConstrainDevices=yes
ConstrainRAMSpace=yes
ConstrainSwapSpace=yes
MaxRAMPercent=90
AllowedSwapSpace=0
AllowedRAMSpace=100
MemorySwappiness=0
MaxSwapPercent=0

/etc/default/grub:
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 cgroup_enable=memory

what other cgroup settings need to be set?
