 OK, using the CORRECT subnet, I can reproduce it:
 
   %fping 10.0.1.99 ; sudo arp -d 10.0.1.99 ; fping 10.0.1.99 ; fping 10.0.1=
 =2E99
 
   %arp 10.0.1.99
   ? (10.0.1.99) at (incomplete) on rl0 expired [ethernet]
 
 The difference is if the unreachable IP is in the arp cache when fping star=
 ts.
 
 Note that ping does the same thing:
 
   %ping 10.0.1.99 ; sudo arp -d 10.0.1.99 ; ping 10.0.1.99 ; ping 10.0.1.99
 
 (and you have to hit ^C to stop every ping process).
 
 It looks like adding -c is a way to get fping to give up sooner:
 
   %fping 10.0.1.99 ; sudo arp -d 10.0.1.99 ; fping 10.0.1.99 ; fping -c 5 1=
 0.0.1.99
   10.0.1.99 is unreachable
   10.0.1.99 (10.0.1.99) deleted
   10.0.1.99 is unreachable
 
   10.0.1.99 : xmt/rcv/%loss =3D 5/0/100%
 
 The OP (Raynaud Alexandre) says this causes problems for zabbix, but only o=
 n FreeBSD.
 
 OP:  Is it one or both of ports/net-mgmt/zabbix{,2}-server?  [Note:  Reply =

 Thanks.
