problem with FOS setup.

Hi

I am configuring FOS setup between two servers with 
IP 192.168.0.221(Master/abel) and IP 192.168.0.222(Slave/cain).

The virtual IP is 192.168.0.253.

	Linux     - Redhat 7.2
	Piranha   - 0.7.0 
	IPVSADM   - v1.18 2001/03/18 (compiled with popt and IPVS v0.8.1)
	Heartbeat - 0.4.9.1

The service setup is Apache/HTTP on port 80.
It works in following cases:

#1. If I shutdown the master, the slave takes over the virtual IP and 
starts the 
HTTP service.

#2. If I kill the pulse running in the master, the slave takes over the 
virtual IP and starts the HTTP service.

#3. If I pull the network cable attached to the master, the slave takes 
over the virtual IP and starts the HTTP service.

However,

#4. If I shutdown the HTTP daemon on the master manually, the slave won't 
take over the vip nor starts the HTTP service.  

The slave server reports following in /var/log/messages.
