-----------------------------------------

             Summary: As NettyServerCnxn.sendResponse() allows all the 
exception to bubble up it can stop main ZK requests processing thread
                 Key: ZOOKEEPER-2549
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2549
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
    Affects Versions: 3.5.1
            Reporter: Yuliya Feldman
            Assignee: Yuliya Feldman


As NettyServerCnxn.sendResponse() allows all the exception to bubble up it can 
stop main ZK requests processing thread and make Zookeeper server look like it 
is hanging, while it just can not process any request anymore.

Idea is to catch all the exceptions in NettyServerCnxn.sendResponse() , convert 
them to IOException and allow it propagating up
