This policer thing seems fine. Can you please write what to police under arp
FOO firewall. It would be great if you can write the complete firewall.

I've seen LAN loops etc cause junos problems.  That's why you need to 
add 'policer arp FOO' under interfaces,unit,family inet.  I'd have 
hoped Juniper would have sane defaults but ....
