I'd like to call attention to a very serious bug introduced in ZooKeeper 3.5.3
https://issues.apache.org/jira/browse/ZOOKEEPER-2901
<https://issues.apache.org/jira/browse/ZOOKEEPER-2901>
If you use server Ids > 127 your ephemeral nodes will behave like TTL nodes in
ZooKeeper 3.5.3 (the TTL will be whatever random value is drawn from the
session ID). I'm working on a fix. But, you can avoid the bug by using Server
Ids <= 127 until this is fixed.
