Any update on this? We are experiencing same thing almost daily and we have to slightly move a node in GUI, then redeploy.

Similar issues:

• When zk restart , kafka-node throw TypeError and Exception: CONNECTION_LOSS[-4] SOHU-Co/kafka-node#250
• kafka-node does not recover from a network interruption with Zookeeper SOHU-Co/kafka-node#279

I gave up waiting on a fix from the author of node-zookeeper-client and wrote my own node-red-contrib-rdkafka module that uses the librdkafka C/C++ library and the new Kafka 0.9/0.10 client API that doesn't require zookeeper anymore.
