In fact, this is not an actual loop.... it's rather an innefiency in update_output_window() when $pkg_interface == "console".

The text is being output to the console, but the variable $static_output is still accumulating text, so update_output_window only prints repeated text, with some additions on every calls. That simply square the amount of character being sent to the console. On a 9600 link... reinstalling squid/squidguard packages takes more than an hour!

My fix is simple, but very ackward on the programming style. I added $static_output as a global variable, and then I clear its content after the "echo":

function update_output_window($text) {
        global $pkg_interface, $static_output;
        $log = ereg_replace("\n", "\\n", $text);
        if($pkg_interface != "console") {
                echo "\n<script language=\"JavaScript\">\nthis.document.forms[0].output.value = \"" . $log . "\";\n";
                                echo "this.document.forms[0].output.scrollTop = this.document.forms[0].output.scrollHeight;\n";
                                echo "</script>";
        } else
        {
                echo $text;
                $static_output="";
        }
        /* ensure that contents are written out */
        ob_flush();
}
