I'm using a org.apache.log4j.RollingFileAppender in order to process and store my log statements and I'm wondering how to get it to never overwrite the output log file?  I left off the log4j.appender.R.MaxBackupIndex configuration and it seems to make one copy then overwrite the original.  Maybelog4j.appender.R.MaxBackupIndex=999999?

I'm testing locally with a max file size of 1KB so I should get a ton of backups... test.log.1, test.log.2...etc.  For some reason the test.log file remains at 1KB, the test.log.1 gets created but grows past the 1KB max that I specified in my config (see below).  Any ideas?


.# The logging properties used for IDE based testing, we want to see
# debug output on the console (use out in that case).
# log4j.rootLogger=INFO, out
log4j.rootCategory=INFO, out, R

log4j.logger.org.springframework=WARN
log4j.logger.com.logging.test=DEBUG

# CONSOLE appender not used by default
log4j.appender.out=org.apache.log4j.ConsoleAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.out.threshold=DEBUG

# Second appender writes to a file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=c://temp//logs//test.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
# Control the maximum log file size
log4j.appender.R.MaxFileSize=1KB
log4j.appender.R.MaxBackupIndex=Integer.MAX_VALUE

There is one backup file by default.
So try with log4j.appender.R.MaxBackupIndex=999999

No - i didn't mean to put that directly in the config file. You need to use the literal value
