Le procédé comprend les étapes suivantes : un dispositif terminal détecte si une anomalie est présente dans un système (S101); dans le cas où une anomalie est détectée, le dispositif terminal détecte stocke les informations de journal correspondant à l'anomalie dans une mémoire vive dynamique synchrone à double débit de données (DDR) (S102); et le dispositif terminal redémarre le système (S103). En mettant en œuvre le procédé fourni par la présente demande, les informations de journal peuvent être rapidement stockées.
