mod_cluster 503s request when JBoss is shutdown instead of doing failover

Solution Verified - Updated -


  • I am getting a Service Unavailable page and a 503 response from Apache/mod_cluster when a JBoss node restarts. Isn't mod cluster supposed to detect that Jboss is down and re-send that request to another node?
