J'ai récemment commencé à obtenir les éléments suivants imprimés dans "kern.log" et syslog.

Je n'ai aucune idée de ce qu'ils signifient, mais ils semblent durer très longtemps, rendant les journaux extrêmement volumineux et, en général, le système ne répond plus.
Cela pourrait-il être lié à une mauvaise mémoire vive ? Je n'ai rien changé à la RAM depuis un certain temps et le système fonctionnait bien depuis quelques mois.
