Perhaps you are out of disk space; post the output from the following:

df -h

Perhaps you just need to restart the daemon, and the service name is
‘rsyslog’ on SLES 21 I believe:

systemctl restart rsyslog

It might be useful if you included other information such as what may have
happened on the 12th, what patches you last applied, if this is working
properly on other similar boxes you have, etc.

Good luck.
