Hi there,

Messages that go to the error log functions in directory server are also echoed to the processes stderr - on RHEL7 since this uses system, stderr is sent to the journal, which in turn then proxies to /var/log/messages.

Details about this can be seen in:

https://www.freedesktop.org/software/systemd/man/systemd.exec.html#

Section "logging and standard input/output".

Note the items "StandardOutput=" and "StandardError=" which default to "journal". If you want to stop this behaviour you can do:

systemctl edit dirsrv@instance.service.

Then add the lines:

[Service]
StandardError=null

This is a per-server and per-service custom override, so should persist through upgrades.

Hope that helps!
