Je viens aussi de mettre : /etc/mysql/mariadb.conf.d/50-server.cnf

[mysqld]
skip-name-resolve

[farias]

Je lance :

# mysqlcheck --auto-repair --optimize --all-databases
...

[farias]

Je comprends pas le problème avec la base.

Pourtant j’ai aucune requete qui dort :

# mysqladmin processlist 
+-----+------+-----------+----+---------+------+----------+------------------+----------+
| Id  | User | Host      | db | Command | Time | State    | Info             | Progress |

| 288 | root | localhost |    | Query   | 0    | starting | show processlist | 0.000    |
+-----+------+-----------+----+---------+------+----------+------------------+----------+

C’est toujours instantanée …
