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
