php 4.2.1 /apache 2.0.36 sessions problems

hello, I've just installed php 4.2.1 and apache 2.0.36 both on my workstation and my server's one. I'm running Slackware Linux 8.0.47 on the server and Slackware Linux 8.1-beta2 on my worstation. It's the same packages, the same configuration on both machines. On my workstation, all work very fine but on the server, I've got this error : Warning: open(/tmp/sess_3bdedaef14affd98363b28132ff552cb, O_RDWR) failed: Invalid argument (22) in /home/httpd/shot/index.php on line 24 Warning: open(/tmp/sess_3bdedaef14affd98363b28132ff552cb, O_RDWR) failed: Invalid argument (22) in Unknown on line 0 Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0 /tmp have rwxrwxrwt rights and I've got 500Mo free on this HDD. How can I correct this ?
