Hi I use the latest mod_cluster(1.0.2 GA) with JBoss 5.1.0.GA server(all) clustered mod_cluster configuration.

My testing envirnoment is:
I created a loopback network interface for testing and added 3 ip addresses on Vista.
1:192.168.1.101:http load balancer
2:192.168.1.102:jboss node1
3:192.168.1.103:jboss node2


I get 503 Service Temporarily Unavailable error by the following cases, and I must wait about 30-60 sec to the httpd begin to route the request to the nodes.

1.when all jboss nodes started and the ear deploy process is finished.(I rarely get 503 error if I delete temp/works directories)
2.sometimes when either node is killed
3.when I killed a node, and try to restart the killed node.

after ~30-60sec it begin to work all cases.


Do you hava any idea?

thx.
