Diego Oliveira commented on ZOOKEEPER-1477:
-------------------------------------------

I did some testing and it appears to be something time related. Running a test 
in debug mode (ZooKeeperTest.testDeleteRecursive) sometimes works. Going a 
little deeper it looks like the channel is going in a broken state and the 
client can not send the next package.

My tests was in ClientCnxnSocketNIO.doIO and NIOServerCnxn.doIO and it looks 
like they are going in silence. I'll do some more test tomorrow and report any 
discovery.

> As background, I was actually investigating some non-deterministic failures 
> when using Netflix's Curator with Java 7 (see 
> https://github.com/Netflix/curator/issues/79). After a while, I figured I 
> should establish a clean ZK baseline first and realized it is actually a ZK 
> issue, not a Curator issue.
> We are trying to migrate to Java 7 but this is a blocking issue for us right 
> now.
