    in the APF I configured not to be executed, exactly thus still ident appears this, has moments that it appears in all top processes

    # Block all ident (tcp 113) requests in and out of the server IF the
    # port is not opened in *_TCP_CPORTS. This uses a reject target to
    # make sure the ident requests terminate quickly. You can see a marked
    # increase in irc and ftp connection performance with this feature.
    BLK_IDENT="1"

    the server all is brought up to date, apf, php, mysql, mod_evasive, etc...

    at some moment with load very high he appears nobody executing netstat, what I can make to verify these problems? What it can be this? Tranks!

    Go on, have a guess
    Shutdown the ident service. IIRC, it's called auth on most RH derivatives and is controlled by editing /etc/xinetd.d/auth and setting disable = yes and then restart xinetd.
