Subject Unable to read additional data from server sessionid...
Date Tue, 08 Apr 2014 22:05:09 GMT
Hi,
  I have a problem in zookeeper, after the session has been established, it
will lose connection in ~1 minute although I see the timeout is set to
600000, i.e 10minutes. What's the possible reasons?
