I think it's unlikely for there to be a memory leak in the JGroups configuration used by Artemis. It's more likely that this OutOfMemoryError is a symptom of a separate issue in the same JVM. However, we need more data to determine what really happened. Did you acquire a heap dump when this happened (e.g. via -XX:+HeapDumpOnOutOfMemoryError)? If so, could you upload somewhere and post the link here for analysis?
Also, can you elaborate on your use-case and describe the circumstances surrounding when this happened?
