original master comes up and takes back VIP

Hi Everyone

I have 2 Dell 2950 servers running ubuntu 10.04 LTS. I installed
ucarp with apt-get install ucarp.

The issue I am having is that one of the machines (whether its set
for master or not) always takes control of the VIP when it is up.

I would like for the system with control of the VIP to keep it until it
goes down and the other system will pick it up.

Is there a setting for this? I have this working on other systems
but can't seem to get it to work on these.

In the log of the machine that steals the VIP back I get this:

We also need:

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 10.04.3 LTS
Release: 10.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
ucarp:
  Installed: 1.5.1-1ubuntu0.1
  Candidate: 1.5.1-1ubuntu0.1
  Version table:
 *** 1.5.1-1ubuntu0.1 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/universe Packages
        100 /var/lib/dpkg/status
     1.5.1-1 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/universe Packages

3) What you expected to happen
I expect the new master to stay as master until it fails. Old master should come back up and slave.

4) What happened instead
The Old master comes up and takes the IP back

Thanks!
