Here is the output of date; ls -la:

[root at missioncontrol mrtg]# date; ls -al

Disk drive isn't full:
[root at missioncontrol mrtg]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              19G   15G  3.4G  82% /
none                  124M   12K  124M   1% /dev/shm
/dev/sdb1              19G   18G  374M  98% /mnt/hdb1

I had emailing to root disabled, my ISP blocks outbount port 25 so I 
couldn't have it email this address.  I've changed it to mail localhost, 
so I'll let it run for a bit and see what happens.  I also changed the 
cron to add logging:

0-59/5 * * * * root env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg 
--logging /var/log/mrtg.log
