Is this a bug? CSF stops every Min

[waterwall]

I start the csf but in exactly 1 min
I see in the cron log

host crond: (root) CMD (/etc/init.d/iptables stop)

then I see my csf is
Firewall Status: Enabled but Stopped

I did not stop the iptables !

It goes on every Min and turns off the csf automatically like a cron

I check my crons but did not find any thing
Where should I look for the problem?

This is resolved

Sorry it was not a bug it was a cron
