    503 Service Temporarily Unavailable - JBoss 4.0.3RC1, Apache

    Phil Clark Newbie

      Ok, before I begin, I have searched many issues in this forum. I found one posting with the same issue but the reply suggestion did not fix my issue (I already had the configuration solution suggested).

      Following the JBoss Mod_jk Wiki (current version), I get 503 Service Temporarlily Unavailable when I try to access ../web-console or ../jmx-console

      Please, Please, Please if anyone has suggestions, I am going nuts.
      If I try xxx:8080/web-console and xxx.com:8080/jmx-console I get the proper display. It was my understanding that if I hit xxx.com/web-console (port 80), apache would forward the request to JBoss/Tomcat. However my head is telling me that xxx.com/web-console and xxx.com/jmx-console context is not defined properly (configuration error - apache is looking to handle these requests).

      I have triple checked the configurations and ports without luck, all looks as the wiki lists.

      Environment: Linux (CentOS 4), Apache 2.0.54 (compiled from source), mod_jk 2.1.14 (compiled from source), JBoss 4.0.3RC1

      My mod_jk.log file prints:

      [Mon Aug 15 20:11:54 2005][error] service::jk_lb_worker.c (703): All tomcat instances failed, no more workers left
