Hi all,

 I am having strange problems with my cron jobs in my CentOS7 kvm
host. After the initial install and first boot, any cron job
configured had run (including cron tasks installed by some rpm
packages).

Last cron's entry log is:


Oct  9 17:01:01 santgraal CROND[9014]: (root) CMD (run-parts /etc/cron.hourly)
Oct  9 17:01:01 santgraal run-parts(/etc/cron.hourly)[9014]: starting 0anacron
Oct  9 17:01:01 santgraal run-parts(/etc/cron.hourly)[9023]: finished 0anacron
Oct  9 17:01:01 santgraal run-parts(/etc/cron.hourly)[9014]: starting
0yum-hourly.cron
Oct  9 17:01:01 santgraal run-parts(/etc/cron.hourly)[9029]: finished
0yum-hourly.cron

cron service is running without problems:

[root at coskvm01 log]# systemctl status crond
crond.service - Command Scheduler
   Loaded: loaded (/usr/lib/systemd/system/crond.service; enabled)
   Active: active (running) since Sun 2015-10-11 11:49:41 UTC; 28min ago
 Main PID: 5124 (crond)
   CGroup: /system.slice/crond.service
           └─5124 /usr/sbin/crond -n

Forcing to run cron tasks editing root's crontab with "crontab -e", it
doesn't works also.

Is this a bug?? Or do I need to install some package apart of:

cronie-1.4.11-13.el7.x86_64
cronie-anacron-1.4.11-13.el7.x86_64
crontabs-1.11-6.20121102git.el7.noarch ???
