[ https://issues.jboss.org/browse/WFLY-6781?page=com.atlassian.jira.plugin.... ] Preeta Kuruvilla commented on WFLY-6781: ---------------------------------------- The cluster that we have is a domain managed cluster where we have domain.xml and host.xml configured on Node1 and only host.xml configured on Node2. The jgroups is a subsystem in the domain.xml for the profile "ha". Regarding our application, we have 2 components - RC.war and SL.war. The JMS is configured on SL. Only component RC is clustered. SL is not clustered. Node 1 has - 2 server instances- RC and SL. <servers> <server name="server-host1-RC" group="main-server-group" auto-start="true"> <jvm name="default"> <heap size="2048m" max-size="2048m"/> <permgen size="512m" max-size="512m"/> <jvm-options> <!--<option value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"/>--> <option value="-XX:CompileCommand=exclude,com/newscale/bfw/signon/filters,AuthenticationFilter"/> <option value="-XX:CompileCommand=exclude,org/apache/xml/dtm/ref/sax2dtm/SAX2DTM,startElement"/> <option value="-XX:CompileCommand=exclude,org/exolab/castor/xml/Marshaller,marshal"/> <option value="-XX:CompileCommand=exclude,org/exolab/castor/xml/Marshaller,marshal"/> <option value="-XX:CompileCommand=exclude,org/apache/xpath/compiler/XPathParser,UnionExpr"/> </jvm-options> </jvm> <socket-bindings socket-binding-group="ha-sockets" port-offset="0"/> </server> <server name="server-host1-SL" group="other-server-group" auto-start="true"> <jvm name="default"> <heap size="2048m" max-size="2048m"/> <permgen size="512m" max-size="512m"/> <jvm-options> <option value="-server"/> </jvm-options> </jvm> <socket-bindings socket-binding-group="standard-sockets" port-offset="0"/> </server> </servers> Node 2 : has only one server instance and that has RC <servers> <server name="server-host2-RC" group="main-server-group" auto-start="true"> <jvm name="default"> <heap size="2048m" max-size="2048m"/> <permgen size="512m" max-size="512m"/> <jvm-options> <!--<option value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"/>--> <option value="-XX:CompileCommand=exclude,com/newscale/bfw/signon/filters,AuthenticationFilter"/> <option value="-XX:CompileCommand=exclude,org/apache/xml/dtm/ref/sax2dtm/SAX2DTM,startElement"/> <option value="-XX:CompileCommand=exclude,org/exolab/castor/xml/Marshaller,marshal"/> <option value="-XX:CompileCommand=exclude,org/exolab/castor/xml/Marshaller,marshal"/> <option value="-XX:CompileCommand=exclude,org/apache/xpath/compiler/XPathParser,UnionExpr"/> </jvm-options> </jvm> <socket-bindings socket-binding-group="ha-sockets" port-offset="0"/> </server> </servers> Now when I say its not working as expected, when we test failover, I mean - the communication of RC and SL is broken. By the way RC communicates remotely with SL using the below url : http-remoting://<ip address of SL which is Node1>:6080/ Just a note:- everything is working properly in production if we don't try disabling network or powering off etc. Let me know if you need any other info.
