I don't see any exception handling in the DBI calls (prepare, execute). try adding something like: 
$sth->execute($i, $data{$i}{cname}, $j, $data{$i}{ports}{$j}{service},
+ $data{$i}{ports}{$j}{banner}) or die "Content-type: text/plain\n\n $
+DBI::errstr";

(the prepare is also an excellent candidate as well)
