Lets look at the code…

# Check acctin reference from INPUT and add/repair if required
CHECK=`$IPTABLES --list INPUT -nv | grep all | grep -c acctin`
…
if [ $CHECK -gt 1 ]; then
	echo Error - multiple IP accounting references detected - trying to fix
	$IPTABLES -D INPUT -j acctin


In other words, it found that there was a rule that appeared more than once in iptables, which was not expected. The -D line removed that. How did it happen? Good question. Theoretically, it should not happen! The only thing that makes sense is if two copies of log_traffic were called by two copies of cron at exactly the same time and they both created rules…

Anyway - ignore it if it doesnt come back again.
