error "Failed opening for inclusion"

sorry if I double posted: Hello, I'm trying to move my apache server from a Fedora Core 1 with PHP V 4.3.8 onto a newly built Centos 5 with PHP 5.1.6, all applications installed by rpms. The www root dir is "/projects/proj2/www/html" and it is a nfs mounted share. During the installation I had moved all of the contents from the remote mount "/projects/proj2/www/html" to a local disk on the CentOS, I tested and I believed I had resolved all issues on the new server. Now when I changed my httpd.conf to point to the nfs share "/projects/proj2/www/html" my php scripts fail, even " phpinfo(); " fails. All errors are identical to the following except for the php file name. ==== *Warning*: Unknown: failed to open stream: Value too large for defined data type in *Unknown* on line *0* *Warning*: Unknown: Failed opening '/projects/proj2/www/html/php_info.php' for inclusion (include_path='.:/usr/share/pear') in *Unknown* on line *0 * ==== Again when I run these same scripts from the local disk I do not received any errors. Any ideas to correcting this problem? Thanks, Lou.
