One app running on one host communicates, but the other app does not. I'm new to JBoss / JGroups (i'm a longtime C++ developer who recently inherited this codebase), so any help is appreciated. These are the errors I see in the log of the app that does not communicate:</div><div><br></div><div><div>2008-03-28 15:29:11,881 WARN [org.jgroups.protocols.pbcast.GMS] merge responses from subgroup coordinators <= 1 ([]).
