The problem is that to be able to restart and join a node with the same hostname and port the cluster must first remove the old incarnation. The downing of the old incarnation is triggered by the new join attempt, but the actual removal can't be done until all unreachable have been downed. In this scenario you still have node3 lingering around as unreachable and hindering the removal of node2.
This is before WeaklyUp is involved. node2 is not accepted to join until the old incarnation is removed. It will work if you restart both node2 and node3. It will also work if you use another port for node2 when restarting it. I don't have a simple solution for supporting this scenario. /Patrik On Tue, Aug 9, 2016 at 9:28 PM, Akka Team <akka.offic...@gmail.com> wrote: > Hi Tom, > > There might be something not working around new incarnations of the same > node (same host and port) rejoining and weakly up, not quite sure if it is > supposed to work.
