    My server is offline for about 30 minutes several times a day.
    It is a 7 debian server, and I followed the tutorial "Perfect debian server 7".
    when the server blocks itself, I came over to access any services (email, ssh, web ...).
    Then, after half an hour, the server becomes available.
    If I restart the server, it is accessible after.
    Thank you for helping,

    (Sorry i'm french)

    Check the fal2ban.log, probably your IP gets banned from time to time for false logins. when your server is behind a NAT router, then you cant use fail2ban as it will block the router IP.

    I checked, but I see only a chineese IP blocked.
    If I stop fail2ban (service fail2ban stop), the problem stay the same.
