RollingFileAppender: Cannot RollFile ... Source does not  exist
---------------------------------------------------------------

                 Key: LOG4NET-82
                 URL: http://issues.apache.org/jira/browse/LOG4NET-82
             Project: Log4net
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 1.2.9
         Environment: Windows 2003 Server
            Reporter: Kenneth Oberleitner


The following logging configuration will produce an endless loop of warnings 
under the following circumstances:

        <appender name="AppRollingFileAppender" 
type="log4net.Appender.RollingFileAppender">
                <param name="Threshold" value="ALL"/>
                <param name="File" value="Log\\Audit\\audit.txt" />
                <param name="AppendToFile" value="true" />
                <param name="MaxSizeRollBackups" value="-1" />
                <param name="RollingStyle" value="Date" />
                <param name="StaticLogFileName" value="true" />
                <param name="CountDirection" value="1" />
                <param name="DatePattern" value=".yyyyMMdd" />
                <layout type="log4net.Layout.PatternLayout">
                        <param name="ConversionPattern" value="%date 
[%c(%property{log4net:HostName})-&lt;%ndc&gt;] - %message%newline" />
                </layout>
        </appender>



1.)     set your system clock back at least three days
2.)     run an application to create the static log file dated 3 days prior
3.)     set your system clock forward a day (i.e. from Monday to Tuesday)
4.)     run the application again, the log file will roll and a new static log 
file is written
5.)     set your system clock forward a day (i.e. from Monday to Tuesday)
6.)     run the application

repeated warnings will be issued until the application is killed

log4net:WARN RollingFileAppender: Cannot RollFile 
[E:\tmp\LoggingFileLockBug\LoggingFileLockBug\bin\Debug\Log\Audit\audit.txt.XXX]
 -> 
[E:\tmp\LoggingFileLockBug\LoggingFileLockBug\bin\Debug\Log\Audit\audit.txt.20060719.XXX].
 Source does not exist

where XXX is infinitely incremented until the process is halted

Two workarounds found so far both involve changing the date pattern. Both 
"yyyyMMdd" and ".yyyy-MM-dd" seem to work without issue.
