I wouldn't recommend using the RollingFileAppender with the MinimalLock. There's no way for one instance of the program to know that another instance has rolled the file. The MinimalLock is slow compared to an ExclusiveLock. The most effecient file based appender across multiple processes would probably be a normal FileAppender with a mutext based lock so the processes can coordinate who is writing to the file. Someone has already implemented such a class:

Hello! Thanks for reply! Yes, it works. But when I log many entries in both processes I receive a log4net:ERROR [RollingFileAppender] Unable to acquire lock on file and after that an INTERNAL ERROR. Append is False but OutputFile ... already exists. There is no way to set the logfile path manual? Or can I specify the folder to user data folder? best regards, Mad
