Here is a patch upgrading to ZooKeeper 3.4.6.  I ran a subset of tests relevant to our ZK integration on both Mac and Windows, and they passed.

> ZOOKEEPER-1702 tracks a client connection management bug.  The bug can cause an unexpected TCP RST that ultimately prevents delivery of a session expiration event.  The symptoms of the bug seem to show up more frequently on Windows than on other platforms (though it's not really a Windows-specific bug).
