Default: False
Range: True or False
Recommended value: True

Use this parameter to control whether the program should check the log file size to see if it has reached the size defined by the max_file_size parameter. If the size of the log file exceeds this parameter, the log file is closed and a new one is opened. If the current date is different from the creation date of the old file (which is part of its name), the new log file will be of the form dbyyyymmdd.log; otherwise the time component will be added to the filename to ensure that the name is unique.
