I have seen this with ncftpput as well, but at least in my case, it
was a warning, and not a fatal error.  Check your ftp server to see if
the backup file has indeed been transferred.

I believe that there is something unusual going on with the checking
on select() return in ncftp3.  If you change every instance of
select() result checking in ftp/ncftp3 from "==1" to ">=1" the problem
seems to go away.

result = select(sfd + 1, NULL, SELECT_TYPE_ARG234 &ss, NULL,
SELECT_TYPE_ARG5 &tv);
-if (result == 1) {
+if (result >= 1) {

Good Luck.
