Dec 28 22:44:12 lachesis rsyslogd: Warning: backward compatibility layer added to following directive to rsyslog.conf: ModLoad imuxsock

-c3 オプションを付けろというので付けてみる。

cp -a /etc/sysconfig/rsyslog /etc/sysconfig/rsyslog.orig
sed -i 's/SYSLOGD_OPTIONS="-m 0"/SYSLOGD_OPTIONS="-c3"/' /etc/sysconfig/rsyslog
/sbin/service rsyslog restart

エラーが出なくなった。
