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 manager_module modules/mod_manager.so

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
