> Hallo,
> We are having sporadic NullPointerException in some of the cassandra nodes in
> cluster (See stacktrace).
> We are having two Datacenter, each having 15 nodes with RF = 2, OS is SLES
> with java-1_6_0-ibm-1.6.0_sr12.0-0.5.1.
> At present only workaround is to stop the application running on same node
> and run repair tool on cassandra. We are unable to identify the cause of
> error.
