This is not packet loss but freebsd shaping the icmp responses to be able to 
let other requests pass as they should
Limiting icmp ping response from 235 to 200 packets/sec
Limiting icmp ping response from 236 to 200 packets/sec
Limiting icmp ping response from 236 to 200 packets/sec
Limiting icmp ping response from 236 to 200 packets/sec

As you can see this is a standard freebsd message when under DoS attac or 
something like that. (type dmesg in /exec.php to get the logs of this)
