I did some testing locally and it turns out that this issue can cause written messages to not be consumed. In my case, i create duplicate commit log file 00000000000000001024 in different path as follows :  When MappedFileQueue initializing, these four files (including duplicate files) will be loaded into mappedFiles, and a self-check error ERROR log will be printed in the checkSelf function.  What's more serious is that when using offset to find MappedFile, the first MappedFile will be returned. If this file is one of the empty files, it means that there is no message here, or it will cause a more serious system exception.  I haven't done more testing, so I'm not sure if this bug only affects consumption, but I think this issue has a big impact on system stability. -- This is an automated message from the Apache Git Service.
