include_path and auto_prepend NOT working right on 4.0.3

Hi, This is an update to my previous question about PHPLIB not working with 4.0.2 (see my 2 messages - subject "Problems with PHPLIB on PHP --> 4.0.1pl2".). Now I have redefined all my include_path and auto_prepend -directives to .htaccess files (using php_value) now everything goes fine after I fire up Apache. Then, after a while when Apache forks more childs and requests are coming steadily PHP starts to act very funny. Opening up a phpinfo() -page show different values on "local value" -row everytime I do a new request (I think this is related to which Apache -child answers the request). Especially I'm interested in include_path and auto_prepend_file -values. This also breaks my applications, sometimes I get "Cannot inherit from undefined class user" from phplib-application which doesn't get it's auto_prepend_file included correctly. Pressing reload several times sometimes gives finally a working page, but clicking a link produces the errors again. My server is: Apache/1.3.12 Ben-SSL/1.39 (Unix) PHP/4.0.3 - OS is Red Hat Linux 6.2. I'm not using the Zend Optimizer. Downgrading to PHP 4.0.1pl2 solves all problems. -Kari
