I resolved the problem by my self:

Hiere the way:

One thing you might not have noticed is that in the Debian/Ubuntu distro, by default PHP disables its session garbage collection mechanism

(eg. the default php.ini contains the line ;session.gc_probability = 0in Ubuntu).

Instead, it runs a cron job every half hour (see the script /etc/cron.d/php5) to purge session files in the /var/lib/php5/ directory. In most cases, this doesn't do the session cleanup job for us as session data may not be saved in files under the /var/lib/php5/ directory (like in Drupal). Thus by default PHP session garbage collection does not run in Debian/Ubuntu as many may expect. To solve this, you can modify the php.ini file by adding the line

session.gc_probability = 1

there. In Drupal, you can also change the settings.php file and add lines such as:

ini_set('session.gc_probability', 1); ini_set('session.gc_divisor', 100);

In addition, then the cron job needs to be disabled . Simply /etc/cron.d/php5 edit with the editor of your choice and comment out the last line :
