Corrupt of sar data files
The most likely problem for this error message is that there are two sa1 sar
processes running at the same time.
With two sa1 processes writing to the file, one will over-write data written by the other, causing corruption in the sar data file which will confuse sar when the file is read. Check that they are not duplicate entries in cron where sa1 and sa2 are running at same time.
Also, Check /var/adm/messages for warning messages from the disk during the time cron is trying to run account /sar. This could indicate a disk is going bad.
