Cron: pam unix (cron:session): session opened/closed for user root by (uid=0)

Go to the /etc/pam.d directory.

Open the file common-session-noninteractive in an editor.

Look for the following line:
   session required

Above this line, add the following:
   session [success=1 default=ignore] service in cron quiet use_uid
   Save the file and exit.

and that should do it!

Hope this helps :)
