jboss/eap docker container error from jgroups stack

Question

While running the docker container using "registry.redhat.io/jboss-eap-7/eap73-openjdk8-openshift-rhel7" base image getting the following error. For testing purpose this is executed as a standalone docker container(using docker runtime) under RHEL7.4

Docker CMD

CMD ["/opt/eap/bin/standalone.sh", "-c", "***-standalone.xml", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

Docker RUN

docker run -p 8002:8002 -p 8003:8003 -t jboss/app:latest

Error

removing pbcast.GMS can be solution. Another solution can be reordering protocols and/or stacks. My problem was TCPPING an last place. After I order it to first place GMS is started too. — László Tóth, Oct 24 '22 at 20:28

I think your udp protocol list isn't complete. My snippet is from wildfly26.1.2 but Ithin PING protocol was the missing.

The order is serious too! See your original standalone-ha.xml!

<stacks>
            <stack name="udp">
                <transport type="UDP" socket-binding="jgroups-udp"/>
                <protocol type="PING"/>
                <protocol type="MERGE3"/>
                <socket-protocol type="FD_SOCK" socket-binding="jgroups-udp-fd"/>
                <protocol type="FD_ALL"/>
                <protocol type="VERIFY_SUSPECT"/>
                <protocol type="pbcast.NAKACK2"/>
                <protocol type="UNICAST3"/>
                <protocol type="pbcast.STABLE"/>
                <protocol type="pbcast.GMS"/>
                <protocol type="UFC"/>
                <protocol type="MFC"/>
                <protocol type="FRAG3"/>
            </stack>
            <stack name="tcp">
                <transport type="TCP" socket-binding="jgroups-tcp"/>
                <socket-protocol type="MPING" socket-binding="jgroups-mping"/>
                <protocol type="MERGE3"/>

                <protocol type="FD_ALL"/>
