cron running twice

Some cronjobs (that running */5 */15 etc) are running twice, like this:

*/5 * * * * /usr/local/cpanel/bin/dcpumon >/dev/null 2>&1
*/15 * * * * /usr/local/cpanel/whostmgr/bin/dnsqueue > /dev/null 2>&1

look my /var/log/cron:

But the cronjobs that run once per day, run fine, like this:
36 0 * * * /scripts/upcp
0 1 * * * /scripts/cpbackup

Someone know why?

My System:
Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
Kernel 2.6.9-42.0.10.ELsmp
Cpanel 10.9.0-R7965

 

Yes, I do it always. but it always run twice again.
