             Summary: [Artemis 2.x upgrade] artemis: artemis/hornetq: memory exhaustion via UDP and JGroups discovery
                 Key: WFWIP-91
                 URL: https://issues.jboss.org/browse/WFWIP-91
             Project: WildFly WIP
          Issue Type: Bug
          Components: Artemis
            Reporter: Miroslav Novak
            Assignee: Martyn Taylor
            Priority: Blocker


When 3rd party tool send multicast messages to Artemis which is configured with UDP Disovery and JGroups Discovery, Artemis creates a huge byte array at receiving the unexpected multicast message. So, it results in heap memory exhaustion, full GC and OutOfMemoryError in the worst case.
