    To day I received a sms alert to my movile telling me that apache was down, and a minute after I received other that it was ok.
    I didnt received at my server log any advice that apache was down, and tried to restart automagically.

    When I look at the apache´s error_log I found a lot of this

    host [-aCdlrTwv] [-c class] [-n] [-N ndots] [-t type] [-W time]
    [-R number] hostname [server]
    -a is equivalent to -v -t ANY
    -c specifies query class for non-IN data
    -C compares SOA records on authoritative nameservers
    -d is equivalent to -v
    -l lists all hosts in a domain, using AXFR
    -i Use the old IN6.INT form of IPv6 reverse lookup
    -N changes the number of dots allowed before root lookup is done
    -r disables recursive processing
    -R specifies number of retries for UDP packets
    -t specifies the query type
    -T enables TCP/IP mode
    -v enables verbose output
    -w specifies to wait forever for a reply
    -W specifies how long to wait for a reply
    host [-aCdlrTwv] [-c class] [-n] [-N ndots] [-t type] [-W time]
    [-R number] hostname [server]
    -a is equivalent to -v -t ANY
    -c specifies query class for non-IN data
    -C compares SOA records on authoritative nameservers
    -d is equivalent to -v
    -l lists all hosts in a domain, using AXFR
    -i Use the old IN6.INT form of IPv6 reverse lookup
    -N changes the number of dots allowed before root lookup is done
    -r disables recursive processing
    -R specifies number of retries for UDP packets
    -t specifies the query type
    -T enables TCP/IP mode
    -v enables verbose output
    -w specifies to wait forever for a reply
    -W specifies how long to wait for a reply

    Apache runs host command from time to time?? Or It might be someone posting host command to do some mess?
    I have mod security installed on my server, If I block the word "host" from posting could affect domains that have the host word in their names??
    Cause dont wanna to filter "host" word and then a person trying to access for example xxxxxxxxhost.com or xxxxxxxxxhosting.com be refused cause it has the host word in their names.

    I wait comments as soon as possible.

    Thanks
