While I thank you for the trust you put in Config, as the package name implies, its purpose is to parse configuration files. Usually, configuration files are not 10Mb large. "If the only tool you have is a hammer, all your problems look like nails". I would recommend you to use a more appropriate solution to parse your 10Mb XML file... Config adds some overhead in order to make accessing the directives and sections more easily. You could give XML_Tree a try maybe. > Using "top" under the console we can see that the http-process uses up to > 180MB memory - then the process quits with the result that I get either > error-output in the browser (see below) or a message "page cannot be > displayed".

Line 152/153 of Config.php are comments, so your error message doesn't really help... > Anyway, I assume that there is a general problem with parsing huge XML-Files > (recursion?) in PHP, isn't there?
