Hi all,

I'm seeing the following error messages in the log from keepalived:

Looks like keepalived crashes and respawns on of the processes which might
be related to the above highlighted lines ie possibly some config parsing
issue. The relevant part of my config is as follows:

vrrp_script dnsmasq-dhcptap0 {
    script "kill -0 $(< /var/run/dnsmasq/dnsmasq-dhcptap0.pid)"
    interval 2
}

vrrp_instance dnsmasq-dhcptap0 {
    state MASTER
    priority 102
    interface vmbr0
    virtual_router_id 47
    advert_int 3
    lvs_sync_daemon_interface eth2
    nopreempt

    unicast_src_ip 192.168.0.185
    unicast_peer {
        192.168.0.186
    }

    notify_master "/etc/keepalived/dnsmasq.sh start dhcptap0 node02"
    notify_backup "/etc/keepalived/dnsmasq.sh stop dhcptap0"

    virtual_ipaddress {
        172.29.240.3/24 dev dhcptap0 scope global
    }

    virtual_routes { 172.29.240.0/24 dev dhcptap0 }

    track_script {
        dnsmasq-dhcptap0
    }
}

The idea is to start dnsmasq process attached to dhcptap0 on IP takeover
for that interface on the MASTER. Now, the log messages are confusing to
me, why would it complain about invalid IP when parsing track_script
statement??

I'm really stamped and probably missing something obvious, any help with
this is appreciated.

Thanks,
Igor
