    Error - All workers in error state

    sree g Newbie



      I have configured mod_cluster as explained in quick start guide.

      I have an apache web server that acts as load balancer and two jboss instances(node1 and node2) which are clustered (vertical cluster).

      Both httpd instance and jboss instances are running on same host .


      started httpd intance and the two jboss instances. The requests are successfully getting routed to one of the instances - say node1


      Now , if I stop node1(to which the requests previously routed, am getting http 503 error . The error persists until i restart httpd instance.

      The web server log (error_log) shows the follwoing error :


      [Thu Oct 21 22:14:27 2010] [error] proxy: AJP: failed to make connection to backend:
      [Thu Oct 21 22:14:27 2010] [error] proxy: CLUSTER: (balancer://mycluster). All workers are in error state
      [Thu Oct 21 22:14:38 2010] [error] proxy: CLUSTER: (balancer://mycluster). All workers are in error state


      Am using mod-cluster 1.0.3 GA, jboss-eap 5.0 and http2.11


      Please help me to understand what is the issue here and how to resolve it . Please find attached httpd.conf, server.xml and mod-cluster-jboss-beans.xml


      Thank you.
