Kafka Borker ID disappears from /borkers/ids

Hi 

Kafka version used : 0.8.2.1 
Zookeeper version: 3.4.6
We have scenario where kafka 's broker in zookeeper path /brokers/ids just disappears.
We see the zookeeper connection active and no network issue.
The zookeeper conection timeout is set to 6000ms in server.properties
Hence Kafka not participating in cluster

Kafka busy spitting below logs
