Problem was crontab failing.
first thing I noticed was

In /var/log/maillog

Then someone suggested to look at /var/log/cron
There I saw errors like

NSSWITCH(nss_method_lookup): nis, passwd_compat, endpwent, not found

Some digging and found that if one takes off NIS from the system one needs 
to change /etc/nsswitch.conf to
group: files
hosts: files dns
networks: files
passwd: files
shells: files

That solved the problem.
However, I find it very interesting that cron fails if it can not send out 
an email.
