Failed to write session data (files).

We have recently turned error_log on and we are getting all PHP errors into a log file. We are using PHP 4.1.2 but this problem was there at earlier versions already. We cannot see any problems on the server but about 30-50 times each they we have the following in the error log: [05-Mar-2002 22:39:38] PHP 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 Our sessions are actually working fine, as far as we can see and /tmp is also the correct path, session files are getting generated and I have no idea what could be wrong. I have also tried to change the session.save_path to a different directories and I have tested different permissions, but nothing change. Any idea what is happening?
