Error when both tracked interfaces go down & then up

If monitored interface(s) on both servers goes down and then up, keepalived
is not bringing up the Virtual IP and just stuck with the error:

Keepalived_vrrp[18056]: cant do IP_DROP_MEMBERSHIP errno=Cannot assign
requested address (99)

In order to make it work again, only restarting the service is helping.
What can be the issue?

- I'm using unicast_peer.
- I'm using version 1.2.10 on CentOS 6.5 64-bit
- I also use net.ipv4.ip_nonlocal_bind = 1 in my sysctl.conf

Here is the config I'm using

! secondary
vrrp_instance LB_1 {
    interface eth0
    virtual_router_id 122
    priority 101

    track_interface {
        ! this is private lan interface
        bond0
    }

    virtual_ipaddress {
        x.x.x.10/27 dev eth0
    }

    unicast_peer {
        10.0.0.122
        10.0.0.123
    }
}

! primary
vrrp_instance LB_2 {
    interface eth0
    virtual_router_id 123
    priority 100

    track_interface {
        ! this is private lan interface
        bond0
    }

    virtual_ipaddress {
        x.x.x.20/27 dev eth0
    }

    unicast_peer {
        10.0.0.122
        10.0.0.123
    }
}
