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

I've tried to introduce sleeps in between INSERTs, even with 30s pauses between them I still see the same in the logs. I have also seen this fail on the very first INSERT.

>             Project: Cassandra
>          Issue Type: Bug
>    Affects Versions: 1.2.6, 2.0 beta 1
>            Reporter: Ryan McGuire

> I get multiple NullPointerException when trying to trace INSERT statements.
> To reproduce:
> {code}
> $ ccm create -v git:trunk
> $ ccm populate -n 3
> $ ccm start
> $ ccm node1 cqlsh < 5668_npe_ddl.cql
> $ ccm node1 cqlsh < 5668_npe_insert.cql
> {code}
> And see many exceptions like this in the logs of node1:
> {code}
> ERROR [WRITE-/127.0.0.3] 2013-06-19 14:54:35,885 OutboundTcpConnection.java (line 197) error writing to /127.0.0.3
> java.lang.NullPointerException
>         at org.apache.cassandra.net.OutboundTcpConnection.writeConnected(OutboundTcpConnection.java:182)
>         at org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:144)
> {code}
> This is similar to CASSANDRA-5658 and is the reason that npe_ddl and npe_insert are separate files.
