memory leak in windows? The more debug log info taked ,the more memory will be occupied

[yangyongzhen]

i have a problem when using log4qt in windows,
The more debug or error log info taked ,the more memory will be occupied.
is there any memory leak in windows? i just did a simple test by qtcreator project，using log4qt version 1.5.0

let me show the picture when running the test for one hour, the memory occupied from 6M to 456M

my log config is:
log4j.rootLogger=DEBUG,daily,console

log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-d [%t] %-5p: %m%n
log4j.appender.logfile.File=./log/uiTest.log
log4j.appender.logfile.ImmediateFlush=FALSE
log4j.appender.logfile.Threshold=DEBUG
log4j.appender.logfile.AppendFile=TRUE

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-d [%t] %-5p: %m%n

log4j.appender.daily=org.apache.log4j.DailyFileAppender
log4j.appender.daily.file=./log/uiTest.log
log4j.appender.daily.appendFile=true
log4j.appender.daily.datePattern=_yyyy_MM_dd
#log4j.appender.daily.keepDays=90
log4j.appender.daily.layout=${log4j.appender.console.layout}
#log4j.appender.daily.layout.dateFormat=${log4j.appender.console.layout.dateFormat}

log4j.appender.daily.layout.ConversionPattern=%-d [%t] %-5p: %m%n
#log4j.appender.daily.layout.contextPrinting=${log4j.appender.console.layout.contextPrinting}

my test example is like this:

`void MainWindow::on_pushButton_clicked()
{
ui->pushButton->setEnabled(false);
QFuture future = QtConcurrent::run(&
{
int count = 0;
while(1)
{
QMutex mutex;
QMutexLocker locker(&mutex);
logger->info("&&&&&on_pushButton_clicked&&&&&&&",FILE,FUNCTION,QString::number(LINE));
QThread::msleep(5);
count++;
}
});
}

void MainWindow::on_pushButton_2_clicked()
{
ui->pushButton_2->setEnabled(false);
QFuture future = QtConcurrent::run(&
{
int count = 0;
while(1)
{
QMutex mutex;
QMutexLocker locker(&mutex);
logger->info("&&&&&on_pushButton_2_clicked&&&&&&&",FILE,FUNCTION,QString::number(LINE));
QThread::msleep(5);
count++;
}
});
}`

i used heob tools in Qtcrator4.15, 64bit, the result is the same,both 32 bit and 64bit have the same probloms:

The more debug log info taked ,the more memory will be occupied
