Hi could you check the state of the following file? It must be with this permissions:
[root@app ~]# ls -l /var/spool/cron/omnileads
-rw------- 1 omnileads omnileads 354 mar 8 11:00 /var/spool/cron/omnileads
Also can you check if omnileads user is in sudoers file?
vi /etc/sudoers
omnileads ALL=(ALL:ALL) ALL
omnileads ALL=(ALL) NOPASSWD: /usr/bin/rsync, /usr/sbin/asterisk
