Bug Description
The bug in question
https:/
This was running on 14.04 LTS (which has 3.4.5). When a snapshot gets large enough, a cluster will not come up because it will timeout while reading the snapshot from a newly elected leader.
This is critical since zookeeper is a basis for many HA systems, so if it doesn't survive a leader crash it becomes useless.
