Cause: sysstat didn't check whether the sa daily data files exist from previous month when appending new statistics to them
Consequence: in some edge cases (as for example short month) sysstat was appending new statistics to the old sa daily data files
Fix: sysstat was modified to check whether the old sa daily data file exists and remove it if it does before appending new data to it
Result: sysstat doesn't append new statistics to the old sa daily data files anymore
