Subject NullPointerException and Java client hang
Date Fri, 30 Jul 2010 10:16:36 GMT
I am getting following exception:

I found
(http://www.mail-archive.com/user@cassandra.apache.org/msg04409.html) in
archived. But no one has replied to this issue. Is this a bug? 

In fact we have a ring of 3 nodes. When this exception occur then our
Java client hang. Can any body please tell me how can i avoid this
situation? We are using cassandra 0.6.3 and hector library for Java
