> Hi,
> We are facing an issue with our daily logs, we have implemented log4net
> logging in our ASP.NET application.
> At mid night when the new file is going to be generated and the old file is
> getting renamed, the process somehow locks the files and the size of the old
> file which was going to be renamed is truncated to size zero.
> Our environment is IIS7.0 Windows server 2008R2, ASP.NET 4.0 and we have
> created multiple domains on IIS pointing to the same website and generating
> their separate logs based on the settings in web config.
> Also we have enabled internal log4net logging and it gave us the error :
> log4net:ERROR [RollingFileAppender] Unable to acquire lock on file
> D:\Project\Frontends\Logs\ UK\WebShoplog.txt.
> The process cannot access the file 'D:\Project\Frontends\Logs\
> UK\WebShoplog.txt' because it is being used by another process.
> I would appreciate any help on this.
> Regards,
> AcetraxSupport
> The Setting we are using in Web config is:
