[jira] Commented: (LOG4NET-82) RollingFileAppender: Cannot RollFile
... Source does not exist
[ http://issues.apache.org/jira/browse/LOG4NET-82?page=comments#action_12422992 ]
Thorbjorn Kvam commented on LOG4NET-82:
---------------------------------------
We've experienced the same issue. We also use the .yyyyMMdd-pattern, and the described bug seem to occur if there are no logfiles from yesterday, but only older logfiles from three days or more back. That is, for instance on my developer computer, if I come back to work on a monday (when my computer have been doing nothing on saturday and sunday), this bug happened.

> 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})-<%ndc>] - %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.
