Troubleshooting
Problem
Several occurrences of the message "Scope libcontainer-nnnnn has no PIDs. Refusing" are reported in /var/log/messages
Cause
These messages have been introduced with latest kubernetes versions, where now cgroup-driver is set to systemd.
These messages are harmless (there is no functional impact).
In next releases, ICP will provide a better separation between kubelet log and other syslog messages, by providing a custom configuration of rsyslog.
Resolving The Problem
As a work-around, you can configure rsyslog to ignore that. Please try this procedure:
cd /etc/rsyslog.d
create a new file "ignore-systemd-session-slice.conf" with following contents (3 rows)
if ($programname == "systemd") and ($msg contains "_systemd_test_default.slice" or$msg contains "systemd-test-default-dependencies.scope") then {
stop
}
and finally...
service rsyslog restart
