health is zero while gw's are reachable

Hi,

 

I have setup a HA pair in our lab. I see that my gateways are "reachable" when I type "show arp".

 

 Gateway Status:
Intf  VLAN     IP-Address          MAC          time-stamp hb status
 1/0   70   010.010.070.001  00:00:5E:00:01:06  1344956928 *  reachable
 1/0   60   010.010.060.001  00:00:5E:00:01:05  1344956928 *  reachable

 

But my healtyscore is zero.

 

Redundancy Protocol Process (v3):
        State                           Active
        Health                          0
        Lowest Local Address            169.254.1.2:9090
        1 peer(s) on 2 socket(s):
        ims-sbc-olo-1-1: v3, Standby, health=0, max silence=1050
                        last received from 169.254.1.1 on eth1:0

 

I'm wondering what could it be the reason?

 

Thanks in advance!
