      Bom dia galera  ;D

      Um dos servidores que tenho está apresentando este erro constantemente:

      Alguém já pegou este erro? Pode ser ataque? Desabilitei o SSH por hora nesse Servidor.

        LFCavalcanti,

        Encontrei esse post do jimp explicando que as vezes esse arquivo pode ficar corrompido:
        http://forum.pfsense.org/index.php/topic,41680.msg222402.html#msg222402

        O problema é que o link que ele postou da solução está dando 404 page not found.

        Ainda assim (esqueci de dizer antes) tenho certeza que após restaurar seu backup esse erro desapareça.

        you would not believe the view up here
