RE: RollingFileAppender stop write to log files

[Gitit Amihud <gi...@yahoo.com>]

Hi Nicko
I get the following exception:
g4net:ERROR [RollingFileAppender] Exception while rolling file [D:\NICECTI\log\RCM.log.25] -> [D:\NICECTI\log\RCM.log.26]
stem.IO.IOException: The process cannot access the file because it is being used by another process.
 at System.IO.__Error.WinIOError(Int32 errorCode, String str)
 at System.IO.__Error.WinIOError()
 at System.IO.FileInfo.MoveTo(String destFileName)
 at log4net.Appender.RollingFileAppender.RollFile(String fromFile, String toFile)
(its not so clear since I took it from the screen.)
the outcome is that new file is not open.
but in the log4net source I saw that there is call for :
this.OpenFile(m_baseFileName, false) in RollOverSize() but again its not open and we dont get logs for days till someone looking for them and dont find.

thanks for your help

If you enable internal logging you should see any exceptions that are

With Windows 2000 AS and VB6 I had a problem with rename when I
implemented a rolling file appender for a program. The old filename
was sometimes(!) locked by the OS for a while after a rename and it
was impossible to create a new file with the old-name until after
a short while (since the system wasn't time critical, I tried it again
in a loop).

Perhaps newer versions of windows keep that feature?
