Bonsoir,
Mon serveur à la maison est dans un drôle d'état !
Serveur Ubuntu 8.04
Pentium III 866 MHz
mémoire 384 MB
MySQL n'est plus en machine
Les stat MUNIN sont arrêtées depuis qques heures
Exim4 semble tourner
Apache semble OK
SSH tourne
Fail2ban tourne, et rien de bien spécial dans son log, juste 2 essais
SSH bloqué, la routine de ce côté là.
uptime : 5 jours (j'avais rebooté pour une mise à jour kernel). Le
serveur n'a donc pas rebooté ce mardi.

Je n'aime pas ces messages !!!
Est la mémoire qui déconne ?
Je ne l'ai pas encore redémarré.
Les sites Web qui n'utilisent pas Drupal ou WordPress, càd pas de MySQL,
répondent correctement.
Ceux qui ont besoin de MySQL sont down (ce n'est pas la catastrophe...)
Je voudrais comprendre...
Si pas d'idée, je reboot sur un Live CD pour lancer un Memtest.
Merci et bonne soirée,
