Servidor lento.

[andunno]

Bom dia pessoal.
Seguinte: agora pouco eu tive um problema de lentidão no servidor da empresa.
Através do TOP verifiquei que o load average estava em mais de 290. Depois que eu dei um boot no servidor, ele voltou ao normal.
Verificando o arquivo /var/log/messages eu detectei as seguintes mensagens:
