> ClientGmsImpl#joinInternal hangs because #firstOfAllClients always returns false when all of the following conditions are satisfied:
> - using JDBC_PING for discovery protocol
> - JGROUPSPING table contains data from previous sessions
> - all of the previous sessions were killed (kill -9)
> - AddressGenerator is not customized
> The sorted set
> {code:java}
> SortedSet<Address> clients=new TreeSet<>();
> {code}
> contains the dead servers discovered from JGROUPSPING. When the new server is added to the sorted set, it never becomes the first in the sorted set.
> Suggestions: either
> a) somehow involve MembershipChangePolicy in ordering strategy, or
> b) make the new server (joiner) the first in the sorted set, or
> c) make UUID addresses to sort depending on their time of creation.
> I've used the following config:
> {code:xml}
> <!--
> TCP based stack, with flow control and message bundling. This is usually used when IP
> multicasting cannot be used in a network, e.g. because it is disabled (routers discard multicast).
> Note that TCP.bind_addr and TCPPING.initial_hosts should be set, possibly via system properties, e.g.

[JBoss JIRA] (WFLY-11807) FD_SOCK socket-binding client mappings do not map to external_addr/port properly
by Paul Ferraro (Jira)
[ https://issues.jboss.org/browse/WFLY-11807?page=com.atlassian.jira.plugin... ]
Paul Ferraro updated WFLY-11807:
--------------------------------
Summary: FD_SOCK socket-binding client mappings do not map to external_addr/port properly (was: Better port configuration for JGroups FD_SOCK)
> FD_SOCK socket-binding client mappings do not map to external_addr/port properly
> --------------------------------------------------------------------------------
>
> Key: WFLY-11807
> URL: https://issues.jboss.org/browse/WFLY-11807
> Project: WildFly
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 14.0.0.Final
> Reporter: Rich DiCroce
> Assignee: Paul Ferraro
> Priority: Major
>
> The JGroups FD_SOCK protocol requires 2 TCP sockets. Older versions of WildFly accepted a socket-binding for this protocol, but that was removed around version 11, apparently because the binding's port number [wasn't actually used|https://access.redhat.com/solutions/3485801].
> Now the port selection is random by default, which is a problem if you've got firewalls to deal with, as noted in the linked document. The suggested workaround is to set the client_bind_port and start_port properties of the protocol, but that has the drawback of not being affected by a socket-binding-group's port-offset. This means that if you want to run 2 WildFly instances on the same box with the same config (which I do, as a developer, to test application code related to clustering), simply changing the port offset is insufficient to get the second instance to start.
> So I'd like to suggest that socket-binding for FD_SOCK be resurrected, given that it can be implemented correctly now. FD_SOCK calls the configured SocketFactory for both the server socket (with name jgroups.fd_sock.srv_sock) and the client socket (with name jgroups.fd.ping_sock), so it should be possible for WildFly to fully manage the socket bindings.
