This implies that the Fileshare Server which was previously writing to this log file terminated abnormally.
Because the Fileshare Server is unable to append to the existing log file, it has been renamed and a new recovery log file has been created. This new recovery log file will be used.
This message implies that the correct sequence of regularly backing up data files and deleting recovery log files is not being performed as the Fileshare Server is being started when a recovery log file already exists.
See the section Rollforward Recovery Logging in the chapter Database Integrity for more details.
