Irrating cron-messages on console

[Johann Spies <jspies@sun.ac.za>]

I am busy installing Debian (sid) on a new PC.

I regularly get cron messages like the following on the console:

cron(pam_unix)[15946]: session opened for user root by (uid=0)
cron(pam_unix)[15945]: session  closed for user root
cron(pam_unix)[15946]: session  closed for user root

What is causing this?

Regards
Johann
