Rotação de log Syslog-ng

Question

eu tenho um problema com o sistema de rotação syslog-ng.

Preciso que minha rotação de arquivos seja agendada uma vez por dia, exemplo:

-rw-r----- 1 root adm  37K Oct 16 192.168.40.240.log
-rw-r----- 1 root adm  83K Oct 15 192.168.40.240.1.log.gz
-rw-r----- 1 root adm  50K Oct 14 192.168.40.240.2.log.gz

Mas agora o resultado é:

-rw-r----- 1 root adm  28K Oct 16 06:23 172.20.252.15.log
-rw-r----- 1 root adm  37K Oct 16 06:21 192.168.40.240.log
-rw-r----- 1 root adm  38K Oct 16 06:21 192.168.40.241.log
-rw-r----- 1 root adm 5.3K Oct 16 06:57 192.168.50.229.log
-rw-r----- 1 root adm  76K Oct 16 06:21 192.168.50.240.log
-rw-r----- 1 root adm 241K Oct 16 07:04 192.168.50.241.log

Conteúdo do arquivo /etc/logrotate.d/syslog-ng

/var/log/zlog/*.log
{
        rotate 3
        daily
        missingok
        notifempty
        compress
        postrotate
                invoke-rc.d syslog-ng reload > /dev/null
        endscript
}

/var/log/syslog
{
        rotate 7
        daily
        missingok
        notifempty
        delaycompress
        compress
        postrotate
                invoke-rc.d syslog-ng reload > /dev/null
        endscript
}

/var/log/mail.info
/var/log/mail.warn
/var/log/mail.err
/var/log/mail.log
/var/log/daemon.log
/var/log/kern.log
/var/log/auth.log
/var/log/user.log
/var/log/lpr.log
/var/log/cron.log
/var/log/debug
/var/log/messages
/var/log/error
{
        rotate 4
        weekly
        missingok
        notifempty
        compress
        delaycompress
        sharedscripts
        postrotate
                invoke-rc.d syslog-ng reload > /dev/null
        endscript
}

Alguém pode me ajudar?

Obrigado
