This was in 10.1.0. What happened was that a kafka broker went down and then this happened on the kafka streaming instance which had connection to this broker. I can send you all logs I got.

Could you try to upgrade to the newly released 0.10.1.0 version and see if this issue goes away? If not I would love to investigate this issue further with you.

Note that when this happen this node stops processing anything and the other nodes seem to want to pick up the load, which brings the whole streaming cluster to a stand still. That’s very worrying. Is a document somewhere describing *in detail* how failover for streaming works?
