             Summary: JGroups: failed setting ip_ttl
                 Key: WFLY-4936
                 URL: https://issues.jboss.org/browse/WFLY-4936
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
            Reporter: Jeff Mesnil
            Assignee: Paul Ferraro


The org.jboss.as.test.clustering.messaging.ClusteredMessagingTestCase.testClusteredQueue test fails on our CI[1].
The messaging resources are using the udp stack from JGroups but JGroups logs a SEVERE message:

I'm not sure whether this is the root cause of the failure but there looks to be an issue with setting up the UDP stack on our CI.
