just out of curiosity, are you saying that: - the memory is freed when you delete the logfiles (with "rm" or something)? - is this some redhat/java combination thing? with my short test nothing like this can be seen under winXP => can you check if RH/java always is caching files (by writing a file yourself with java.io classes)
my test: public static void main(String[] args) { int i = 0; while (true) { log.debug("test test " + i++); } } log4j-config: log4j.rootCategory=DEBUG, TRACE log4j.appender.TRACE=org.apache.log4j.RollingFileAppender log4j.appender.TRACE.File=test.log log4j.appender.TRACE.MaxFileSize=100MB log4j.appender.TRACE.MaxBackupIndex=10 log4j.appender.TRACE.layout=org.apache.log4j.PatternLayout log4j.appender.TRACE.layout.ConversionPattern=%d %C - %F %M (%L) [%t] %-5p %c - %m%n cheers patrick > -----Ursprüngliche Nachricht----- > Von: Wozniak, Marcin [mailto:[EMAIL PROTECTED] > Gesendet: Donnerstag, 22.
