-----------------------------------

             Summary: Number of RollBackups files extremely increases
                 Key: LOG4NET-519
                 URL: https://issues.apache.org/jira/browse/LOG4NET-519
             Project: Log4net
          Issue Type: Bug
    Affects Versions: 1.2.15
         Environment: Win 7
            Reporter: Pavel Kilik
            Priority: Minor


We have defined LogManager with repositories. In repositories are the RollingFileAppenders. For each RollingFileAppender are defined values:
{code:title=C#, init value settings|borderStyle=solid}
        AppendToFile = true;
        RollingStyle = RollingFileAppender.RollingMode.Size;
        MaxSizeRollBackups = maxFileCount;
        MaximumFileSize = maxFileSize;
{code}
It works without problems and number of RollBackups files is equal to MaxSizeRollBackups. If values of MaxSizeRollBackups and MaximumFileSize are runtime changed, the MaxSizeRollBackups is ignored, RollBackups files are not deleted  and number of RollBackups files extremely increases. There can be more than 1500 files!!!

RollingFileAppender change in our C# code:

{code:title=C#, runtime value changing|borderStyle=solid}
  foreach(var v in LogManager.GetRepository(CreateRepositoryName(id)).GetAppenders())
  {
	if(v is RollingFileAppender)
	{
	  RollingFileAppender roll = v as RollingFileAppender;
	  if (roll.MaximumFileSize != filesize)
	  {
		roll.MaximumFileSize = filesize;
	  }
	  if (roll.MaxSizeRollBackups != filecount)
	  {
		roll.MaxSizeRollBackups = filecount;
	  }
	}
  }
{code}

Part of log4net logging. There are 22 RollBackups, but maxSizeRollBackups is set to 2. The value of maxSizeRollBackups is ignored.

{code:title=log4net logging|borderStyle=solid}
log4net: rolling over count [2058]
log4net: maxSizeRollBackups [2]
log4net: curSizeRollBackups [22]
log4net: countDirection [-1]
