RHEL 6 sa and sar log file size

I am trying to figure out why sa and sar log files are much larger on one of our servers. Basically double the size -rw-r--r-- 1 root root 100M Feb 5 23:59 sa05 -rw-r--r-- 1 root root 100M Feb 6 23:59 sa06 -rw-r--r-- 1 root root 100M Feb 7 23:59 sa07 -rw-r--r-- 1 root root 141M Feb 5 23:53 sar05 -rw-r--r-- 1 root root 141M Feb 6 23:53 sar06 -rw-r--r-- 1 root root 141M Feb 7 23:53 sar07 compare to another server -rw-r--r-- 1 root root 34M Feb 5 23:59 sa05 -rw-r--r-- 1 root root 34M Feb 6 23:59 sa06 -rw-r--r-- 1 root root 34M Feb 7 23:59 sa07 -rw-r--r-- 1 root root 57M Feb 5 23:53 sar05 -rw-r--r-- 1 root root 57M Feb 6 23:53 sar06 -rw-r--r-- 1 root root 57M Feb 7 23:53 sar07 Anyone sees this before and any idea to reduce sa/sar log size?
