  • 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.



  • Valeu Johnnybe, vou testar amanhã e dou um Feedback aqui.
