Problem seen with logrotate

Hi all,

I have configured logrotate to logorotate every 12 hour. The configurations are as follows.

/etc/cron.d/config
-------------------------

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=""
HOME=/root
0 */12 * * * root logrotate /etc/logrotate.d/test

/etc/logrotate.d/test
--------------------------------
/var/ipaccess/nanobsc/CheckIn/application/log/*.log {
daily
size 5M
missingok
copytruncate
rotate 10
}

But this log files are rotated every hour. I verified the /etc/cron.hourly folder as well to check for any other configurations. But they seem to be OK. Could somebody explain me why this behaviour.

Regds,
