Subject [jira] Created: (LOG4NET-198) Memory leak on a very basic code
Date Fri, 06 Feb 2009 23:32:59 GMT
Memory leak on a very basic code
--------------------------------

                 Key: LOG4NET-198
                 URL: https://issues.apache.org/jira/browse/LOG4NET-198
             Project: Log4net
          Issue Type: Test
          Components: Core
    Affects Versions: 1.2.10
         Environment: windows xp sp3
            Reporter: rauzy


I build a simple form with a single button that start a timer execute every second, the task
of this timer is to execute the following line:

log.Debug("Hello");

and I observe a memory leak.

See Below.


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using log4net;
using log4net.Config;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(Form1));
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            XmlConfigurator.Configure();
            FreqTimers.Start();
        }

        private void FreqTimers_Tick(object sender, EventArgs e)
        {
            log.Debug("demo");
        }
    }
}

with an app.config like 


<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"
/>
  </configSections>
  <log4net debug="true">
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="C:\\Temp\\TestMailer.log" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%-5p %d - %m  %-18.18M %n" />
      </layout>
    </appender>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>
</configuration>

If you monitor the application, you see that the memory usage increase. Why? I can post the
source solution if needed.
