Hi,
The last RHEL3 update pack contains a mailman package. I'm using that on a new mailserver and found a little problem with cron when starting/ stopping the mailman service. RedHat moves the mailman crontab in and out every time, however, crond only notes the 'move in', not the 'move out. This is because the /etc/cron.d/ timestamp only changes by a 'move in'.
My fix: add
rm -f $DST_CRON_SCRIPT
as the first line in the function RemoveCron() in /etc/init.d/mailman.
Cheers,
