c0rga apparently had a full hard drive. There was 1 Gig log file in /var/log directory, called Xorg.0.log.old which I deleted which freed up about 20% of the hard drive. This let me then modify the crontab file (which previously had been complaining about no room on disk to make edits).
I updated the crontab to look at the new scripts location, updated the RGA script itself to write to the new log location, and then created a soft link in the /opt directory to /cvs/cds/rtcds on c0rga.
The RGA script should now be running again once a day.
