Re: SASL problem with 3.4.4 Java client
This may be related.  We are not using SSL, but the underlying cause may be the same: socket disconnection or failure to deliver data from the underlying channel.

We experienced connection drops (after about ~3000ms) with Curator 1.1.18 and ZK 3.4.4. on openjdk 6 (on Linux), and JDK 7u7 on OS X.

Oracle JVM 1.6.0_32 on Linux and v. 1.6.0_35 on OS X, seem to work.

Here's the error we get over and over.

==========================================
I'm having some trouble with the 3.4.4 Java client on Linux (openjdk 6
or 7, debian or ubuntu).  It doesn't seem to successfully connect to a
server -- this goes for zkCli as well as custom code that uses the
client jar.  On OSX, it *does* connect.

I've collected the DEBUG-level log output for the process of
connecting to my development Zookeeper node (also running 3.4.4),
waiting until a Connected event arrives, and sending getChildren("/").
The Linux version logs that it will not use SASL and then keeps
deferring the getChildren request "until SASL authentication
completes".  The exact same (fat) jar running on OSX complains a few
times about being "unable to locate a login configuration" but doesn't
wait.

Using the 3.4.3 client library or earlier does successfully connect,
logging only the one message about JAAS that was changed as a result
of ZOOKEEPER-1510.

On Linux, the output of the 3.4.4 client is:
