This cronjob deletes old session files and generally has no noticeable
effect on the system (assuming you've not modified it). Before we go
any further, it would be good to confirm that this is what it's doing
- the content of the file should look something like this:

    # /etc/cron.d/php5: crontab fragment for php5
    #  This purges session files older than X, where X is defined in seconds
    #  as the largest value of session.gc_maxlifetime from all your php.ini
    #  files, or 24 minutes if not defined.  See /usr/lib/php5/maxlifetime
    
    MAILTO = "" 
    # Look for and purge old sessions every 30 minutes
    09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete 1>&2 2>/dev/null

Does it?
