I have two different (i386 v AMD) Debian boxes and have the same problem. logrotate won't rotate my logs automatically. It works fine when i force it manually like
/usr/sbin/logrotate -f /etc/logrotate.conf
but it's not okay for me.
Settings wasn't modified (at least i didn't modified them), the AMD box is a fresh install yet won't do it's job.
If you have noticed a similar problem, please help me.
