    1. Courierpop3login:authentication error: input/output error
    2. freshclam: getpetch: cant download daily-7199cdiff from
    3. sshd[32097]: invalid user guest for user root
    4. postfix/smtpd[11414]:lost connection after CONNECT from localhost[]
    5. postfix/local[11304]: warning:pipe-command-read: read time limit exceeded
    6. high mem -empty, lowmem reserve low, swap pages,...

    What are the outputs of
    df -h
