Issue

We have multiple JBoss environments that use different httpd/mod_cluster proxies. The JBoss servers log errors that suggest they are trying to connect to the other mod_cluster proxies:
```
ERROR [org.jboss.modcluster] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) MODCLUSTER000042: Error null sending INFO command to otherproxy.com/127.0.0.1:6666, configuration will be reset: null
```
Why is this and how can we correct it?
The mod_cluster share configuration across multiple httpd instances even advertise parameter has set to false in Tomcat server configuration,why?
