topic: Re: coould anyone tell me why this zookeeper Exception happens?

When a zk client closes its session it sends a close session request to the
server. In some cases the client may not finalize it's side of the close
before the server closes the session - including closing the socket. If this
happens the client may output this message (read rc of
-1 means "end of stream"). Nothing to worry about in this context.
