I have 3 EC2 instances each running 1 exhibitor/zookeeper.\r\n\r\nI use a autoscaling group to replace lost servers. If I manually terminate a server, a new one is launched.  But in the process my remaining ZK nodes stop communicating with each other, they show up as yellow. My load balancer which is checking each server on port 2181 also goes down, so I'm assuming this means I lose all zookeeper connectivity for about 10-15 mins.\r\n\r\nIs that normal?\r\n\r\n"}}
