>                 Key: LOG4NET-465
>                 URL: https://issues.apache.org/jira/browse/LOG4NET-465
>             Project: Log4net
>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 1.2.13
>         Environment: asp.net 4.0
>            Reporter: Michel Emond
>         Attachments: RollingFileAppender.diff, config.xml

> This is the issue described in LOG4NET-378
> h2. Reproduction steps
> # Setup a web application using the settings from the attached config.xml file
> # Notice the rolling style set to Composite
> # Start and use the application
> # The log files pile up in the folder
> # Restart IIS
> # Keep using the application
> Expected result
> - The rolling continues on or after the last file
> Actual result
> - The rolling restarts at index 1 and overwrites the existing files
> h2. Solution
> See the attached files:
> - config.xml
> - patch with a fix proposal
> The original bug fix addresses the issue in the InitializeFromOneFile() method.
> However, the GetWildcardPatternForFile() method also needs the baseFileName to be adjusted with the datePattern so the proper files are searched.
> I placed a file path fix in the DetermineCurSizeRollBackups() method, so it's then passed down to the two other methods and everyone gets happy.
> Here's a calling stack sample:
> {code}
> DetermineCurSizeRollBackups()
> |
> +--GetExistingFiles()
> |  +--GetWildcardPatternForFile()
> |
> +--InitializeRollBackups()
>    +--InitializeFromOneFile()
> {code}
