[jira] [Commented] (ZOOKEEPER-1043) Looped NPE at
org.apache.zookeeper.server.NIOServerCnxn$Factory.run(NIOServerCnxn.java:244)

César Álvarez Núñez commented on ZOOKEEPER-1043:
------------------------------------------------
Today we have had the same problem and the origin seems to be the followin exception:

{noformat}
As you can see, it seems to exist some correlation between the SocketException and the looped NPE.
