It could mean that both your data nodes are using same port and although they are one different hosts, seems suspicious. There are other ways to configure port numbers to use. Normally you only configure PortNumber of ndb_mgmd unless you want to use the default 1186. You snipped quite a lot of logs so it's hard to tell which ports you are using. / Magnus
