disconnected from zk server upon client start
Hi,

I'm using the zk Java client to connect to zk server on the localhost.
The client got disconnected right away after the connection is
established and the session got expired. What is the reason that the
server terminates the connection? Is there any flag I should specify
when creating the client? The client is created with:

             zk = new ZooKeeper("127.0.0.1:2181", 7000, new Watcher() {
                 @Override
                 public void process(WatchedEvent event) {
                     KeeperState ks = event.getState();
                     logger.debug("zk state:" + ks);
                     if ( ks == KeeperState.SyncConnected ) {
                         logger.debug("zk client connected");
                         com.peaxy.event.Event e = new
com.peaxy.event.Event(EventType.DCS_READY, null);
EventService.getInstance().publish(e);
                     }
                 }
             });

And the following is the server log:
