I remember with Panther and Tiger I was told to occasionally leave my Mac on overnight so that the cron jobs that clean out the system log files could run... either that or I was supposed to run a program to clean the logs manually. I was wondering if this was still the case in Leopard? Do the system cleaning cron jobs only run at night, or has Apple addressed this issue? (maybe they could run at startup instead, or in Disk Utility?).
