Hi markus, try to stop your indexing/update processes and restart your ZooKeeper instances (not all at the same time of course). This is what I do in these cases and helped me so far.

Hello, One node is behaving badly, at least according to the logs, but the node is green in the cluster overview although the logs claim recovery fails all the time. It is not the first time this message pops up in the logs of one of the nodes, why can it not talk to Zookeeper? I miss a reason. The cluster is not extremely busy at the moment, we allow plenty of file descriptors, there are no firewall restrictions, i cannot think of any problem in our infrastructure. What's going on? What can i do? Can the error be explained a bit further?
