Hi Friends,

I am getting the following errors on the cluster at my site. I am using the RHEL 5 cluster suite on for HA of my database and web server. My cluster service at one point in a day restarts the service automatically as it cannot find the virtual ip. Can you please guide me on this issue. On checking my logs i.e. /var/log/messages it shows me the following info:

The cluster is doing its job, isn't it? When the ip address is not reachable, it restarts the service. Are you using a correct ip? Maybe another machine in the network tries to put that ip up.

Thanks in advance and expecting your reply at the earliest.
