I just started getting these emails from one of my servers:

title -
Cron <root@server> /usr/local/bandmin/bandmin

body -
iptables: Chain already exists

Anyone know what this is?

This solution was posted at Burstnet forums:
Run the following commands:

/etc/rc.d/init.d/iptables stop
/etc/rc.d/init.d/iptables start

This will flush them and recreate.

If the stop/start doesn't work for you try running

/scripts/sysup
