Hi

I am now trying to run several services on two nodes.

The setup is as below:
VIP1: 10.226.193.230
VIP2: 10.226.193.250

Real IP 1: 10.226.193.189
Real IP 2: 10.226.193.190

Service 1 is running on both Node1 and Node 2, monitored by ldirectord.

And I have a problem when trying to configure more services, eg.
serviceA running on node 1
serviceB running on node 2

My haresources is configured like this:
*************************************************
node1 \
       10.226.193.230 \
       10.226.193.250 \
       ldirectord::/etc/ha.d/ldirectord.cf #service 1 is
loadbalancing inside ldirectord.cf

node1 serviceA
node2 serviceB
*************************************************

During my test, whenever I shutdown heartbeat on one node, I will get
error msg on the other node:
*****************************************************
