GitHub user FreeAndNil added a comment to the discussion: Question about asynchronous writing by log4net
@yktnoriri I've converted you issue into a discussion. I was able to reproduce your problem once, but only once. Can you set a breakpoint in https://github.com/apache/logging-log4net/blob/172e875622c0d4ba845ad6dace02c001687de96f/src/log4net/Appender/RollingFileAppender.cs#L634 and add a condition for the "wrong" fileName?
