It looks like the error message is not needed. When lftp forks into background,
its child processes become parentless, that is why waitpid fails. Fortunately,
lftp checks for process existence by kill(pid,0), and still can determine
if the process terminate. There is remote opportunity for some other process
to occupy the pid, does anybody has an idea how to cope with that?
Anyway, this patch should fix the reported problem.
