There is already opened issue on Github, more details can be found here.

This issue is related with cgroup-driver. In newest Kubernetes version is set to systemd instead of cgroupfs.

One workaround is to configure rsyslog. Steps are well sescribed on this site. Below short version:

$ cd /etc/rsyslog.d

Create a file ignore-systemd-session-slice.conf with content:

if ($programname == "systemd") and ($msg contains "_systemd_test_default.slice" or $msg contains "systemd-test-default-dependencies.scope") then {
  stop
}

After that service rsyslog must be restarted.

$ service rsyslog restart

Another way is to use cgroupfs as cgroup-driver. This also was discussed on this Github thread.
