No idea, this was not expected at all. The new server just crashed, and I had to reboot it manually when I came home.
And without any apparent reason : I've spent the last hour looking through all my logs and monitoring data, but nothing shows anything abnormal before the crash...
If knowledge can create problems, it is not through ignorance that we can solve them. Si le savoir peut créer des problèmes, ce n'est pas l'ignorance qui les résoudra.
