[389-users] errors messages in /var/log/messges

H! We have set up a new 389DS instance (389-ds-1.2.2-6.el7.noarch) on CentOS7. Messages from the "errors" log file are also getting written into /var/log/messages. The instances (389-ds-1.2.2-1.el6.noarch) on CentOS6 do not do that. I have checked the rsyslog facilities local0-local7 and none of them are responsible. What could be causing this? Kind regards, Mitja Mihelič
