Warning: Folder $folder already lockf'd Error: Package $package does not implement $method. Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package. Error: Unable to check lock file $filename for $folder: $! To check whether the filename is used to flock a folder, the file must be opened. Apparently this fails, which does not mean that the folder is locked neither that it is unlocked. Error: Unable to open FcntlLock lock file $filename for $folder: $! For FcntlLock style locking, a folder it must be opened, which does not succeed for the specified reason. Error: Will never get a FcntlLock lock at $filename for $folder: $! Tried to lock the folder, but it did not succeed. The error code received from the OS indicates that it will not succeed ever, so we do not need to try again. SEE ALSO
