Anthony why networkmanager is installed in zenlb2? Did you install it?
Zen service manages interfaces and farms and networkmanager is not installed by
default so this zen is modified and other services are managing the system in
place of zen.
Also your attached logs show a dhclient is executed and this also is disabled
by default...

Subject: Re: [Zenloadbalancer-support] Losing ip from NIC
have a look in:
dmesg
/var/log/messages
/var/log/syslog
Configure manually the IP and check it, because the zen service is starting the
ip but the operative system or the hypervisor (if zenlb is a vm) is powering
off the eth0, maybe duplicated ip

Hello,
any VRRP/cluster ? Maybe switch see mac address twice and block port?
If zen is stopped on node, do you loose also network?
