    JBoss shutdown without any log

    alexandre russel Newbie

      We plan to deploy app in a farm with apache as a front using mod_jk. At the moment we test using apache2, mod_jk 1.2.18-3, and jboss 4.0.4. Just One instance of apache and jboss on the same machine.
      We configured mod_jk so request are sent to jboss. It works for few requests then we get an error, mod_jk on apache gives the following message:
      [Fri May 18 09:25:38 2007] [10792:19376] [error] ajp_service::jk_ajp_common.c (1794): Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=ajp13w failed

      using netstat -a we see that all jboss services (8009, 1098, ..) are closed, all connection to mysql are established instead of listen. Trying to connect to jboss using twiddle gives a not connected error. All this make us think that JBoss has just shut down.

      We set the log of org.jboss and org.apache to DEBUG, the last log are:
      2007-05-18 10:15:12,881 DEBUG [org.apache.jk.common.HandlerRequest] Invoke returned 0
      2007-05-18 10:15:12,881 DEBUG [org.apache.jk.common.ChannelSocket] receive()

      2007-05-18 10:15:14,879 DEBUG [org.apache.catalina.session.ManagerBase] End expire sessions StandardManager processingTime 1 expired sessions: 0

      2007-05-18 10:15:14,879 DEBUG [org.apache.catalina.session.ManagerBase] End expire sessions StandardManager processingTime 0 expired sessions: 0

      we can't find a single message telling us that jboss has shut down.
      It just look that jboss has shutdown, cleanly and very suddenly.
      Does anyone has an idea on where to look for clues ?
      thanks

          We finally tracked down the problem. It has nothing to do with mod_jk.
          One of our app is using jboss rules and the jvm crashes always at the same place:
