-----------------------------------------
Xiawei,
It is good to open jira's with issues in zookeeper but its much better to
provide more information on the issue you are facing. Like in this case, it
would be very helpful to get the stack trace on the Sendworker.run thread that
died and also the jstack of the zookeeper process.
