Failed to start container on centos 6.10 (32bit)

Hi,
im trying to setup lxc on an centos 6.10 (32 bit) vps.
i have installed lxc and lxc-templates using yum and created a debian (stretch 32bit) container using following command

lxc-create -t download -n c1

and everything is ok. but when i want to start this container using following command:

lxc-start -n c1

i get following error message:

lxc-start -n c1
lxc-start: cgfs.c: handle_cgroup_settings: 2153 Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
