Estou tendo um comportamento super estranho ... A carga da CPU do meu computador passa pelo telhado (> 4 em uma máquina 8core), mas não há processo que esteja levando muito CPU (consulte a imagem anexada) Embora o núcleo da máquina esteja com carga alta estar entre 30-70% de oscilação.
Esse comportamento aparece após X minutos de uso do computador (aleatório, variando de alguns minutos a algumas horas). Além disso, depois que isso aconteceu, o computador acabará por congelar.
Estou com perda aqui, tive esse problema em 15.04, atualizado para 15.10, mesmo.
A máquina tem essas partes: Placa-mãe: Asus Z10PE-D8WS CPU: CPU Intel (R) Xeon (R) E5-1620 v3 a 3,50 GHz RAM: 2x Kingston 16Go PC4-2133 CL15 - Registo ECC (KVR21R15D4 / 16) HDD: 2x 2Para ATA ST2000DM001-1ER1 no RAID 0
A única coisa estranha que encontrei foram aquelas linhas no log do kernel:

Ajuda!
Obrigado por me lembrar de terminar isso!
De fato, depois de olhar as linhas, notei que: slot: 0 foi o problema. Assumindo que era uma memória ruim, eu peguei (Slots são alocados pela sua placa-mãe, ou pelo menos no meu, o slot zero era o slot 1 da placa-mãe)
Assim eu retirei, testei por 48 horas, e nenhum erro apareceu. Enviou a memória RAM para garantia, conseguiu um novo de volta.
Tudo é perfeito no país das maravilhas!
Ainda está rastreando esse problema? Parece que você tem um módulo de memória ruim, a máquina faz uma pausa apenas aguardando o hardware para corrigir esse erro por si só. Pode ser necessário tentar remover ou substituir a memória na sua primeira CPU, segundo canal e primeiro slot. Consulte: link
Espero que ajude.
