why crontab process run repeated auto at sometimes

Question

sometimes, we found our server's cron process auto repeated, repeated 2 or 3 times

when use ps command, I get this:

server_xx14:~ # ps aux | grep cron
root      2596  0.0  0.0  11188   392 ?        Ss    2009   0:25 /usr/sbin/cron
root     21706  0.0  0.0  20812   944 ?        S    09:30   0:00 /usr/sbin/cron
root     23437  0.0  0.0  20812   944 ?        S    09:40   0:00 /usr/sbin/cron

I only want just one cron to running, how can i fix this problem? thx!
