Zookeepr quorum and electing a leader.

Having 5 zookeeper server instances in the cluster, is it possible that all
zookeeper instances will stop responding if one of the zookeeper instances
stops responding?

By stops responding I mean the state in which zookeeper service does not
send TCP responses back to other zookeeper instances.

Kind regards
Greg.

I've never seen this. Are there jira/logs/... that you can point to that
would help identify the version and potentially reproduce?

Something similar we have seen during network/VM glitches and making Solr
nodes go down/in a recovery state.
