    JBOSS 7.1 + mod_cluster 1.3.1 Final + Apache/2.4.6  : IO error sending command CONFIG to proxy

    Meehaf A Newbie

      Hello,

       

      I am trying to configure JBOSS clustering using mod_cluster module and is seeing the below error in the logs

      I have two httpd servers in front of Jboss servers one acting as a Master and other as Slave. Below is the apache configuration:

       

       

      -------------------------------------------------------------------------------------------------------------

      LoadModule cluster_slotmem_module modules/mod_cluster_slotmem.so

      LoadModule manager_module modules/mod_manager.so

      LoadModule advertise_module modules/mod_advertise.so

       

      Listen 192.168.1.100:80

      Listen 192.168.1.100:10001

      I am using Apache server "Apache/2.4.6 (CentOS)" and mod_cluster version "mod_cluster-1.3.1.Final", the JBOSS version is "jboss-as-7.1.1.Final". I saw a similar thread JBoss errors after moving to Apache 2.4 and mod_cluster 1.2.1.Final but the case seems to be unresolved - [MODCLUSTER-353] SocketTimeoutException in DefaultMCMPHandler when using httpd 2.4.x - JBoss Issue Tracker

       

      I have attached a screenshot of what I see in the apache server.

       

      Can someone please help to identify and resolve the problem?

       

      Kind Regards,

      Meehaf
