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

Hello Bhumir,

you are right. Of course the lastest improvment cannot work. After a roll over, 
all waiting appenders need to see if the file reference has changed. Now they 
check only the old reference.

I will try to create a fix now

> Hi,
> We have developed a web application and integrated with log4php, which is 
> used by hundred of users. When the size of log file exceed the maximum file 
> size, it calls rollOver() function to create back up file for log file and 
> truncate the current log file. 
> We faced one error while renaming the file from "filename" to "filename.1". 
> This error is generated when hundred of users are accessing the application 
> at the same time. The error is generated as below:
> PHP Warning:  
> rename(C:\PHP\errors/Test_Module.log,C:\PHP\errors/Test_Module.log.1) [<a 
> href='function.rename'>function.rename</a>]: Permission denied in 
> C:\Inetpub\wwwroot\Test_Application\System\System_Logger\log4php\src\main\php\appenders\LoggerAppenderRollingFile.php
>  on line 140
> Also, back up of log files are not created in sequence when above warning is 
> generated. For example, log file "Test_Module.log" is already exists and 
> rollOver() function is called to create new back up file then it creates 
> "Test_Module.log.4" instead of "Test_Module.log.1".
> Moreover, log file has given all the required permissions and it works fine 
> while appending the logs.
> We would appreciate if you can help us by providing a solution or work-around 
> for resolving this issue.
> Please let me know if more details are required.
> Thank you.
> Best regards,
> Bhumir Sheth
