I see similar messages fairly often. I believe "Success" is what you get when you use strerror() to translate an errno of 0 (success) on a Linux/UNIX machine with English localization. So this contradictory message is what happens when the programmer uses an errno-printing function (perror() or something custom) to indicate an error that wasn't actually due to a failure that sets errno.
