RE: slapd shuts down for no reason

Hi,

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.

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:

notifempty
missingok
create  0640 ldap cerebrum
start   0

/ldap/log/syslog/openldap.log {
       size=250M
       rotate  2500
       compress
       delaycompress
       lastaction
               /bin/kill -s HUP syslogd
       endscript
}
