Ldirectord running on both nodes shouldn't be a problem.
But if you want it to only run on the active Linux Director
heartbeat should be able to manage this.

1. Make sure that your haresource file looks something like this:

2. Make sure that the haresources (and other heartbeat configuration
   files) are _identical_ on both linux directors.

3. Make sure that ldirectord is not configured to be started by init.

No that is a new one to me. The bringing up of the interface and
sending of arp is done by the same resource (IPaddr) so it supprises
me that one happens without the other.
