Hi Hans, We were also facing this issue and the reason was that there were spikes in the network connectivity between nodes due to which the master was not able to discover the data nodes ,during zen discovery and hence removed those nodes and brought them back. You can try to increase the discovery.zen.ping.timeout that defaults to 3 seconds ,this should fix the issue.
