Subject disconnected from zk server upon client start
Date Thu, 11 Oct 2012 01:14:48 GMT
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:
