je n'arrive pas à lire ton image, les écritures sont trop petites, est ce que tu peux faire un zoom sur la zone rouge ?

C'est à cause du redimensionnement qui est fait par le site ou par le navigateur. Tu peux afficher directement l'image originale avec https://pix.debian-fr.xyz/upload/origin ... 947642.png et zoomer avec le navigateur si nécessaire.

Je recopie ici la ligne rouge complète :

Code : Tout sélectionner

MEM | tot 8.0G | free 1.9G |   | cache 399.4M | dirty 0.0M |   | buff 0.0M | slab 137.5M |   | slrec 62.6M |   | shmem 2.3G |   | shrss 0.0M |   | shswp 0.0M |   |   | vmbal 0.0M |   |   | hptot 0.0M |   | hpuse 0.0M |

Le seul trux inhabituel c'est la mémoire cache qui est basse. Tu as peu de pages mémoires en cache, alors qu'il y a encore 1,9 G d'utilisable

C'est bien ce qu'il me semblait. Pourtant, la ligne reste rouge, même lorsque je ne rencontre pas le problème des commandes qui échouent avec "Cannot allocate memory".

Le man de atop indique:

Code : Tout sélectionner

COLORS
       For the resource consumption on system level, atop uses colors to indicate that a critical occupation percentage has been (almost) reached. 
[...]
        Memory
            An occupation percentage of 90% is considered `critical'.  Notice that this occupation percentage is the accumulated memory consumption of the kernel (including slab) and all processes; the memory for the page cache (`cache' and `buff' in the MEM-line) and the reclaimable part of the slab (`slrec`) is not implied!
[...]
       When a resource exceeds its critical occupation percentage, the concerning values in the screen line are colored red by default.
Je n'ai pas de de fichier /etc/atoprc ou ~/.atoprc qui puisse venir écraser la configuration par défault. Selon la doc, la seule raison pour laquelle cette ligne devrait être rouge est "An occupation percentage of 90%", ce qui n'est manifestement pas le cas...

Je n'ai pas de swap. Est-ce que ça pourrait être lié ? J'en crée un et regarde ce que ça change.
EDIT : Je ne peux pas créer de swap sur la machine (VPS)...

Peut-être devrais-je m'approcher du support de OVH pour diagnostiquer le problème.

Tu as aussi le shmem qui est élevé, je ne sais pas trop à quoi correspond cette mémoire partagée
Ca à l'air lié au tmpfs, et il y a des paramètres kernel pour la gérer

J'ai joué un peu avec les paramètres du kernel sans vraiment savoir ce que je faisais. Pas de résultat positif.

J'ai aussi ouvert un ticket chez OVH, et j'ai reçu une réponse très rapidement. Malheureusement, la réponse se résume à "ce modèle de VPS est vieux, il vaut mieux mettre le produit à jour vers une version plus récente". Il faut voir ce que ça donne question prix. Et ma curiosité n'est pas satisfaite !

Pas génial question prix... Pour avoir les mêmes specs (RAM, nombre de coeurs et espace disque), il faut payer le double !

J'ai finalement réussi à capturer un strace d'un `su` échoué. Le voici ci-dessous, pour information. Sinon, je vais migrer mon VPS ce weekend, donc on peut considérer le problème comme clos. Même si non résolu...

Dunatotatos a écrit : write(2, "su: \303\211chec d'authentification\n", 30su: Échec d'authentification
Si je ne m'abuse il s'agit d'un échec d'authentification (mot de passé erroné), pas de l'erreur système mentionnée dans le message initial.

Ah oui, en effet... Il semblerait que lancer su avec strace retourne forcément cette erreur, même si le mot de passe est correct. Je vais tenter avec une autre commande qui échoue.
