[ULTRAMONKEY-USERS] [lvs-users] Ultramonkey heartbeat not starting ldirectord automatically

[Aslan Carlos]

There node are down? check you director network configuration and in the
servers behind the director, because have something wrong on each one.
The Ldirectord are trying to do to checking the service mysql,but  your
server are down, they remove from IPVS, so while you don't fix the
network access to ldirectord to do the checks, it'll remove all servers
down. :s


best regard.
