    mod_cluster issue after JBoss restart

      I am running mod_cluster 1.2.0.Final (under Apache) with JBoss EAP 6.  When I first start Apache and JBoss everything works fine, but after restarting JBoss all attempts to access the application result in a 503 error until Apache is restarted as well.  I think my httpd configuration is fairly standard:

       

      <IfModule manager_module>

        Listen *:6666

        <VirtualHost *:6666>

          <Location />

           Order deny,allow

           Allow from all

          </Location>

       

          KeepAliveTimeout 300

          MaxKeepAliveRequests 0

          AdvertiseGroup 239.255.100.102

          EnableMCPMReceive

                LogLevel debug

       

          <Location /mod_cluster_manager>

             SetHandler mod_cluster-manager

             Order deny,allow

             Allow from all

          </Location>

       

        </VirtualHost>

      </IfModule>

       

      as is my modcluster configuration in JBoss (my modcluster socket-binding has been modified to use the same multicast address as in the AdvertiseGroup above):

       

              <subsystem xmlns="urn:jboss:domain:modcluster:1.1">

                  <mod-cluster-config advertise-socket="modcluster" connector="ajp">

                      <dynamic-load-provider>

                          <load-metric type="busyness"/>

                      </dynamic-load-provider>

                  </mod-cluster-config>

              </subsystem>

       

      My issue unfolds like this:

       

      1.  I start both Apache and JBoss and everything hooks up correctly - I can see my node in mod_cluster_manager and application requests work.  Hooray!

      2.  Upon shutting down JBoss I see the expected DISABLE-APP, STOP-APP and REMOVE-APP messages in my httpd logs and my node no longer displays in mod_cluster_manager.  So far this is still what I expect.

      3.  When I restart JBoss I see the following messages in my httpd logs and my node re-appears in mod_cluster_manager.  So far so good.

      4.  Unfortunately, when I attempt to access the application I now get 503 errors and see the following in my httpd logs.  This behaviour persists until I restart Apache.

       

      [Thu Aug 23 11:40:01 2012] [error] proxy: CLUSTER: (balancer://mycluster). All workers are in error state

       

      There are no other messages in the log preceding this to indicate what might be going on, nor is there anything of interest in the JBoss logs.  Can anyone help?

       

      The only thing I can see that 'may' be contributing is the JBoss EAP 6 claims to be running version 1.2.1.Final of mod_cluster - could there be any version conflicts between this and 1.2.0.Final running on Apache?  I cannot alter what JBoss is running and have been unable to find a 1.2.1 release to download for Apache.

          LogLevel debug is in the VirtualHost the request/reponse are outside or in another VirtualHost so we can't see what is going wrong.

          The part of the log above looks OK it should have worked.

            Thanks for the quick response - I should have noticed I'd only enabled logging for the virtual host.  I'm home for the weekend now but will try and turn more logging on on Monday and see how I go.

              So after turning on more debug logging I'm not really any closer to resolving the issue.  For successful requests (prior to restarting JBoss) I see the following log output:

              .....(More logging representing a successful request)

               

              After restarting JBoss I see all of the ENABLE-APP traffic (already posted above) and the following additional debug logging when attempt to access the application

              Any ideas?  For completeness, here's the entire log from the point JBoss is shut down - there's multiple web applications so it's a little verbose:

                I have managed to resolve this issue by upgrading my mod_cluster binaries from 1.2.0.Final to the latest 1.2.2.Beta1 build from the Jenkins server at http://hudson.jboss.org/hudson/job/mod_cluster-windows/ - although I have no idea what may have changed to fix the problem.  Are there any non-Beta versions later than 1.2.0.Final I can try?  I'm guessing there's a 1.2.1 release out there somewhere but I can't find it anywhere to download.
