Order by bigint myisam is not ordered. Why? - mariadb

Question

I had to use bigint instead of regular int. After creating the new table it bahaves unusual. See details below.
MariaDB [user]> select * from dmn_base2 ORDER BY id DESC limit 4;
+------------+-----------------------+----------------+--------+
| id | domain | base | tld_id |
+------------+-----------------------+----------------+--------+
| 1975224411 | bank-3dsecure.com | bank-3dsecure | 4 |
| 466015797 | bank-365.se | bank-365 | 378 |
| 1711908528 | bank-2projects.online | bank-2projects | 20 |
| 27739599 | bank-2580.com | bank-2580 | 4 |
+------------+-----------------------+----------------+--------+
^----this is unusual
It uses index:
MariaDB [user]> explain select * from dmn_base2 ORDER BY id DESC limit 4;
+------+-------------+-----------+-------+---------------+---------+---------+------+------+-------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+------+-------------+-----------+-------+---------------+---------+---------+------+------+-------+
| 1 | SIMPLE | dmn_base2 | index | NULL | PRIMARY | 8 | NULL | 4 | |
+------+-------------+-----------+-------+---------------+---------+---------+------+------+-------+
Structure of the table:
MariaDB [user]> show columns from dmn_base2;
+--------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------+--------------+------+-----+---------+-------+
| id | bigint(20) | NO | PRI | NULL | |

+--------+--------------+------+-----+---------+-------+
MariaDB [capturesipbee]> SHOW CREATE TABLE dmn_base2;

query does not finished, killing has no effect after 5 hours

| 36 | root | localhost | db | Killed | 21107 | Sending data | select * from dmn_base2 ORDER BY id DESC limit 5 | 0.000 |
my guess is: broken index file?
I have copied the database to other device. The same query works as expected.
mysql> select * from dmn_base order by id desc limit 4;

Answer 1

I had to update MariaDB. (10.1->10-6)
As I use Plesk I refer to this articles:
Which MariaDB versions are supported by Plesk?
