sar does not log when two instances(sa1 and sa2) are executed

Issue

• When /usr/lib64/sa/sa1 and sa2 are executed by using crond service on our customer's system, /var/log/sa/sarXX is not created.
• /etc/cron.d/sysstat is as follows:

 0-59/1 * * * * root /usr/lib64/sa/sa1 1 1    <== Execute sa1 in one minute interval.
 53 23 * * * root /usr/lib64/sa/sa2 -A
