Fopen wrapper cannot resolve ip

The PHP4 installed on our production machine apparently cannot resolve ip addresses when using "fopen wrapper" functions. For example if I issue a command like: $page = file ("http://www.any_host_here.com"); I obtain the following error: Warning: file("http://www.any_host_here.com") - Bad file descriptor in /z/www/test/fopen.php on line 2 On the contrary if I issue the following: $page = file ("http://100.50.25.1"); there is no problem. Obviously PHP is compiled with fopen wrappers on and network and dns are ok (ping or wget for example work well resolving correctly ip numbers). The machine runs BSD/OS 4.1 / PHP 4.0.3pl1 / Apache 1.3.11 I don't want to use absolute ip to open external files! Any ideas, suggestion ? Thanks in advance.
