this happens only if there are Artemis servers in cluster with the same ID. Artemis generates its ID at first start. Did you copy Artemis's journal directory among the servers? Or started the wildfly 10 server, stopped and then copied.
I'm not suire if it's possible to change ID of servers. Only way i'm aware to fix this is to delete Artemis journal directories and start again.
Thanks, Mirek, that helped me
