Bonjour

J'ai un problème sur serveur mysql avec une dizaine de base de
site de commerce en ligne
j'ai assez régulièrement des plantages de mysql

quelqu'un peut il me dire si le parametrage ci dessous est correct

Euh, dis-nous plutôt quels genre de plantages est-ce que tu as? Est-ce que ça plante quand il y a trop d'accès concurrents?

Sinon essaye aussi de regarder dans les stats de phpmyadmin (onglet "Etat"); quelques infos seraient les bienvenues pour pouvoir t'aider...
