Plantage Maxcale en charge

Bonjour,

Nous avons tenté de mettre en prod dans la soirée du 16 au 17/06, Maxscale mais ce dernier n'a pas tenu la charge après plusieurs heures. voici les logs d'erreur :

AFAIK this the 'Attempt ...' messages are related to issues with the databases itself. Does this cause any problems to the production?

Now related to the crash at ~2AM which is the reason you opened this ticket. this is what we can see in the log:

Que peut-on faire pour résoudre ce problème ?

En vous remerciant
