[Maria-discuss] Aborted connection (Unknown error)

Hi all, I'm getting annoying errors when I want to switch clients from MySQL to MariaDB. I use Debian Wheezy, and MariaDB 10.0 repositories, then I install mariadb-common & libmariadbclient. Then I restart services using MySQL Client Library and I have a lot of warnings like these on my MariaDB Server (with Galera or not) : [Warning] Aborted connection 136305 to db: 'db' user: 'user' host: 'xx.xx.xx.xx' (Unknown error) I do not have more information in logs. This is not a network problem, because it occurs with 127.0.0.1 too. What do I miss ? Thank you a lot. Florent
