The sa errors are actually part of system monitor package, sysstat.  The 
errors are being generated due to a daily cron entry located 
in /etc/crontab:

  5 19 * * * root /usr/lib/sa/sa2 -A &

What this does it generate a text file based on data file.  What redhat 
shipped only generates that datafile on the weekends.  Therefore you won't 
get errors on saturday and sunday.  I removed that entry and I added the 
following entry to /etc/crontab:

  0 * * * * root /usr/lib/sa/sa1 600 6 &

This will generate the data file and update it 6 times every 10 minutes and 
runs every hour.

The sa files are located in /var/log/sa.  The number represents the day of 
the month.  The sa files are data and the sar files are the converted text 
file.

Hope this helps.
