Logs : PHP Notice: Undefined index: HTTP_HOST

[-Tony-]

Hello
joomla 3.4.1
serveur apache
J'ai remarqué un truc un peu space dans mes logs.

error.log :

[Thu Jul 02 09:12:03 2015] [error] [client 37.128.xxx.xx] PHP Notice:  Undefined index: HTTP_HOST in /var/www/libraries/joomla/application/web.php on line 863
[Thu Jul 02 09:12:04 2015] [error] [client 37.128.xxx.xx] PHP Notice:  Undefined index: HTTP_HOST in /var/www/libraries/joomla/uri/uri.php on line 85

Reviens régulièrement et pas avec la même IP

Correspondant a :

web.php

        /*
         * There are some differences in the way that Apache and IIS populate server environment variables.  To
         * properly detect the requested URI we need to adjust our algorithm based on whether or not we are getting
         * information from Apache or IIS.
         */

        // If PHP_SELF and REQUEST_URI are both populated then we will assume "Apache Mode".
        if (!empty($_SERVER['PHP_SELF']) && !empty($_SERVER['REQUEST_URI']))
        {
            // The URI is built from the HTTP_HOST and REQUEST_URI environment variables in an Apache environment.
            $uri = $scheme . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
        }
        // If not in "Apache Mode" we will assume that we are in an IIS environment and proceed.
        else
        {
            // IIS uses the SCRIPT_NAME variable instead of a REQUEST_URI variable... thanks, MS
            $uri = $scheme . $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME']; //ligne 863

            // If the QUERY_STRING variable exists append it to the URI string.
            if (isset($_SERVER['QUERY_STRING']) && !empty($_SERVER['QUERY_STRING']))
            {
                $uri .= '?' . $_SERVER['QUERY_STRING'];
            }
        }

        return trim($uri);
    } 

uri.php

                /*
                 * Since we are assigning the URI from the server variables, we first need

                 */

                if (!empty($_SERVER['PHP_SELF']) && !empty($_SERVER['REQUEST_URI']))
                {
                    // To build the entire URI we need to prepend the protocol, and the http host
                    // to the URI string.
                    $theURI = 'http' . $https . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; //ligne 85
                }
                else

                     * QUERY_STRING environment variables.
                     *
                     * IIS uses the SCRIPT_NAME variable instead of a REQUEST_URI variable... thanks, MS
                     */
                    $theURI = 'http' . $https . $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'];

                    // If the query string exists append it to the URI string
                    if (isset($_SERVER['QUERY_STRING']) && !empty($_SERVER['QUERY_STRING']))
                    {
                        $theURI .= '?' . $_SERVER['QUERY_STRING'];
                    }
                } 

J'ai comparé avec access.log, et c'est toujours un HEAD qui fait apparaitre l'erreur, jamais un POST ni un GET

179.191.xxx.xx - - [02/Jul/2015:09:04:41 +0200] "HEAD / HTTP/1.0" 200 579 "-" "-"

Une idée ?

Re : Logs : PHP Notice: Undefined index: HTTP_HOST

Mes recherches m'ont menées à ce post : http://forum.joomla.org/viewtopic.ph...&view=previous
Mais le fichier finder_indexer.php à été fixé comme tel depuis donc ce n'est pas ca

Et également rapport à nagios, mais je n'ai pas ca sur le serveur.

Bref pas plus avancé pour l'instant...
