Hi Weezer!
Have you tried MacJanitor??? It's FREE and can be downloaded from:
http://www.versiontracker.com Type MacJanitor into the Search box... it will take you directly to the download page
The following is what MacJanitor does.
MacJanitor runs the system's 3 maintenance scripts.
Daily Script
If the rwho system has been configured, clear out the old files in /var/rwho
Clear out files old files and directories in the /tmp and /var/tmp directories
Remove system messages older than 21 days
If system accounting is on, process the accounting files and gather daily statistics
Backup the NetInfo database
Output the disk capacities and storage available
Show which filesystems haven't had 'dump' performed on them in a while (archaic)
Show accumulated network statistics and network uptime (ruptime)
Rotate the system.log file and restart the syslog process
Clear out the webserver log files older than a week
Run the /etc/daily.local script if it exists
Run a /etc/security check script if it exists
Weekly Script
If the /usr/libexec/locate.updatedb database exists, update the 'locate' database
If the /usr/libexec/makewhatis.local file exists, rebuilt the 'whatis' database
Rotate the following log files: ftp.log, lookupd.log, lpr.log, mail.log, netinfo.log
Restart the syslog process
Run the /etc/weekly.local script if it exists
Monthly Script
Run the login accounting process
Rotate the wtmp log files
Restart the syslog daemon
Run the /etc/monthly.local script if it exists
See if that helps!
