Jul 20 08:07:48 sles12sp5 systemd[1]: Starting Security Auditing Service...

After a system reboot, sometimes the system does not log entries in /var/log/audit.log. The timestamp of the log file remains unchanged or the same as the reboot time. 

Within /var/log/messages following messages are observed:

kauditd hold queue overflow
kernel: kauditd_printk_skb: 11 callbacks suppressed


As workaround a restart of auditd will solve it temporarily:
systemctl restart auditd.service
A fix has been released for SUSE Linux Enterprise Server 12 SP5 with kernel version 4.12.14-122.127.1 or higher.


Root cause is a race condition in the communication between kernel and auditd instance that also led to kernel overflow messages.
