Maximum File Size - supported in log4j FileAppender

Question

I have a requirement that I need to store audit information in a TEXT file. I planned to write the audit information using Apache Log4j.

By default, maximum file size is 10MB(If you don't mention explicitly). And if you define explicitly, you can define any value upto GB(even 1000GB). But think, when you open this file, your machine must have an equal amount of RAM. So you have to take this into consideration before choosing file size. An example here

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logging.log
log4j.appender.file.MaxFileSize=100GB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

FileAppender doesn't contain any field for setting file size. But its subclasses RollingFileAppender and DailyFileAppender contains.
