log4cplus configuration file, file max size doesn't work

Question

i have create a config file for log4cplus and its works but MaxFileSize don't do anything so my files keep growing without taking in considaration my limit . this is my code :

### logs.properties

# root logger

log4cplus.rootLogger=INFO, Main

# specific logger

log4cplus.logger.myloggerINFO, Main
log4cplus.additivity.mylogger=false

# appender that automatically rolls files

log4cplus.appender.Main=log4cplus::DailyRollingFileAppender
log4cplus.appender.Main.Schedule=DAILY
log4cplus.appender.Main.File=mylogs.log
log4cplus.appender.Main.Append=true
log4cplus.appender.Main.MaxBackupIndex=100
log4cplus.appender.Main.MaxFileSize=100KB
log4cplus.appender.Main.layout=log4cplus::PatternLayout
log4cplus.appender.Main.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n

log4cplus.logger.myLoggerName=DEBUG, R2
log4cplus.appender.R2=log4cplus::RollingFileAppender
log4cplus.appender.R2.File=logs/webaccess.log
log4cplus.appender.R2.Append=true
log4cplus.appender.R2.MaxBackupIndex=5
log4cplus.appender.R2.MaxFileSize=5KB 
log4cplus.appender.R2.layout=log4cplus::PatternLayout
log4cplus.appender.R2.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n

this is the example of list of files i get :

webaccess.log | 7kb even if max=5
mylogs.log    | 0
mylogs.log.2012-11-26 | 1k
mylogs.log.2012-11-26.1   |1k
...
mylogs.log.2012-11-26.45  | 1k 
he create new files even if max=100k 

so if you see anything wrong please tell me thanks

Answer 1

Log4cplus' DailyRollingFileAppender does not observe MaxFileSize property. At the moment either you choose rolling log files by time or by size, you cannot have both at the same time.

EDIT 1:

The appender R2 does not work because there is a lower bound for the allowed MaxFileSize value: const long MINIMUM_ROLLING_LOG_SIZE = 200*1024L; This is 200 KiB. It in the log4cplus source from the start (or really long) and I have never felt a need to remove the limit.
