Hello List,
I have a very simple HAProxy configuration that is balancing two web servers.
This configuration was failing over from node 1 to node 2, and from node 2 to
node 1.. but now the only node that displays the web sites is node 1. If node 1
is stopped and node 2 is the only load balancer running going to the urls that
worked under node 1 displays page not found.
This is a little puzzling because the configurations between the two nodes is
identical. The only difference between the two configuration files are the node
and description entries.
## lb1 haproxy config -- this load balancer works - it shows the sites

Heartbeat is being provided by keepalived but that appears to be functioning
well.
Well this is a slightly embarrassing situation but I greatly appreciate any
help you may have to offer.
Thanks in advance!
Tim
