load is unbalanced with multiple mod_jk/httpd loadbalancers

Issue

• He have a hardware balancer balancing multiple httpd/mod_jk servers, which balance multiple JBoss nodes. We see unbalanced load because each httpd server seems to prefer the same worker (the first one listed in the balance_workers). So for example, httpd1 gets a request and routes it to node1. Then httpd2 gets a request and still routes it to node1. Is there any way to share load information across the httpd servers or is there any other way to correct this?
