Only for logrotate.

of which logs exactly ?

The -HUP in the logrotate.conf was not working. Even on the command line kill the slapd process with a -HUP was not working. Putting the /etc/init.d/slapd stop; sleep 5, /etc/init.d/slapd start does make sense when nothing else was working. We tried numerous different iterations, this was the only thing that worked for us. It worked...so, thus it makes sense.

restarting slapd does not make sense for syslog aus syslog has the file handle open, not slapd.

From my understanding it also does not make sense for auditlog.

Greetings Christian

Fall back to legacy unix...sorry logrotate is more appropriate. Yes, yours is very similar to how ours looked and it would stop the daemon fine, and rotate the log but would not restart. I modified it to look

like this:

.... /etc/init.d/slapd stop; sleep 5; /etc/init.d/slapd start

why are you stopping and starting slapd ? This does not make any sense.

Commenting out the "/bin/kill -s HUP syslogd".

Now, it does what it is supposed to do.

We had a similar issue a few months back. I discovered that it was dying at about the same time. Come to find out it was syslog rotation that was doing it. Syslog sends a HUP signal to rotate the logs and restart a daemon. I had to put a sleep statement in the syslog

for slapd.

Your syslog rotates logs? On our host (RedHat) it's logrotate which does that. And it's logrotate which must kill -HUP syslogd, to make syslogd close and reopen the log. From logrotate.conf:
