I'm using log4net in my project and there is one problem. The major function of the program takes a long time and I use logging to save information about it. I use FileAppender for saving log to file.
My application is on the shared(local) folder and there could be several instances of the application running from one path. In this case I could log information only from the first program, other instances of my applications couldn't log info because log file is locked.
When I'm using "log4net.Appender.FileAppender+MinimalLock" option there are cases of information loss. Not all logs from both instances are saved to file.
How can I solve this problem and log info from parallel instances? Also what about performance degradation when I use "MinimalLock" option?
Thanks. Hope for your help.

RollingFileAppender means the system creates a log file based on your filters, this way you can have log files based on dates (one file each day), or get the file splitted into small chunks when it hits certain size.
Is log4net thread-safe? Yes, log4net is thread-safe.
For log4net to know where to store your log messages, you add one or more appenders to your configuration. An appender is a C# class that can transform a log message, including its properties, and persist it somewhere. Examples of appenders are the console, a file, a database, an API call, elmah.io, etc.
Simply include the process id of the application in the log file name. Different instances of your app will then log to different files. Here is an example:
<appender name="MyRollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString">
<conversionPattern value="log_%processid.log" />
</file>
