icmppingloss Host is down=success

[Gray]

Hi! Sorry for my english. I have next problem:
I want to check icmp lost packet to some host on the same direct connect network as Zabbix server, 192.168.15.0/24 for example: 192.168.15.10 - Zabbix and 192.168.15.20 on target host. I have an item:
icmppingloss[{IPADDRESS},10,200,900,1000]

So the problem -- if host is down fping sometimes says

z# /usr/local/sbin/fping 192.168.15.21
192.168.15.21 is unreachable

and sometimes

z# /usr/local/sbin/fping 192.168.15.21
192.168.15.21 error while sending ping: Host is down

192.168.15.21 is unreachable

So then i've got "Host is down" message function icmppingloss return 0%, like I have no any ping losses. I think 100% should be returned in this case.
In FreeBSD "host is down" is usual showned then host is in direct connect network and local arp table have entry like this:

? (192.168.15.21) at (incomplete) on fxp0 expired [ethernet].

So result in attachment: host changes state from Up to Down frequently then is totaly Down.

FreeBSD 8.2-RELEASE, Zabbix Server v1.8.8 (revision 21965) (28 September 2011) from source, fping: Version 2.4b2_to $Date: 2002/01/16 00:33:42

It's look like an fping problem. Anyway you can cheet with construction like this icmppingsec[{HOST.IP},3,,,,avg].avg(#2)}=0

icmppingsec return "0" only when host is down in my case.
