Hi Markus, Finally found out my issue in this post, thanks a lot.. So i have similar issues where the initial leader always back to be leader once restarted... So there is not a real solution dealing with akka leader related component right where getLeader will return the appropriate leader (who become leader stay leader until it does) ? Your workaround solution is to use the oldest node instead?
