    Automatic redeploy failed

    marcodanti Newbie

      I just ran into the following problem in a two nodes cluster:

       

      • on node stw-2, open a deployed .war under standalone/deployments to change a parameter into a web.xml file
      • save changed file
      • on the server.log file, see this

          15:37:00,982 INFO  [org.jboss.web] (ServerService Thread Pool -- 98) JBAS018224: Unregister web context: /STW

          15:37:00,985 INFO  [org.jboss.modcluster] (ServerService Thread Pool -- 98) MODCLUSTER000021: All pending requests drained from default-host:/STW in 0.0 seconds

       

      This is not normal, because the AS server did not go on and redeploy the updated .war. The same operations repeated on the other node (stw-1) trigger the following log:

          15:40:43,793 INFO  [org.jboss.web] (ServerService Thread Pool -- 101) JBAS018224: Unregister web context: /STW

          15:40:43,796 INFO  [org.jboss.modcluster] (ServerService Thread Pool -- 101) MODCLUSTER000021: All pending requests drained from default-host:/STW in 0.0 seconds

      which is what was expected. The first node however remained like that. In the mod_cluster-manager page, I see

       

      mod_cluster/1.2.6.Final

      start of "httpd.conf" configuration

      The setup I am using is: two AS-7.2.0.Final nodes in cluster, behind a httpd-2.4.6 reverse proxy with mod_cluster-1.2.6.Final (on both AS7 and httpd), all running on SLES-11.


      I had to restart the node that failed to redeploy

          Update: I retried this several times; normally it works fine, but once in a while it fails. This time, I did not restart the server and after exactly 10 minutes the log showed the following error:

            Radoslav Husar Master

            So if I understand correctly, the hot-redeployment sometimes fails to redeploy successfully? (you can test to access the app directly, not via reverse proxy)

             

            Or just mod_cluster fails to register the context?

             

            So restart (or reload) fixed the problem?

              Ops, I forgot to specify in the original post that when I 'restarted' the server that failed to redeploy, that was not a normal restart. I had to hard kill the jboss process (kill -9) because it seemed to be hanged somewhere.

                Radoslav Husar Master

                Could you please replicate the situation and get a thread dump of the java process and attach it here? (jstack)

                • 5. Re: Re: Automatic redeploy failed
                  Radoslav Husar Master

                  Also... can you try to undeploy completely first and then do a deploy? (therefore there will be no "Replaced deployment" log message)

                  • 6. Re: Re: Re: Automatic redeploy failed
                    marcodanti Newbie

                    OK I got two stack traces: the first was done right after the server locked up after saying "All pernding requests drained...". The I let it alone for 10 minutes, after which it outputs the "Operation ("full-replace-deployment") failed" exception and after that I catched the second trace.

                      And here is the server.log content, to complete the picture, with some comments of mine:

                         Trigger auto-redeploy by touching a .war
