• We are migrating our application from AS to EAP version on production environment. But we are facing very strange behaviour. Our set up is with two JBoss EAP node cluster and Apache mod_cluster as front end. When we start node one, node get started and when we start another, it starts throwing exception. This is true when we do visa versa, but sometimes both get started without any error.
