Vijay commented on CASSANDRA-4713:
----------------------------------

Yes the error starts popping up after 0ea28c858e3f693dc44d38cd4306e02049d01ce8

It is simple to reproduce:
1) Use stress to add data to a single node cluster
2) run ./apache-cassandra-1.2.0-beta1-SNAPSHOT/bin/sstableloader -d 127.0.0.1 /var/lib/cassandra/data/Keyspace1/Standard1/

You will see the issue. after this patch or before 0ea28c858e3f693dc44d38cd4306e02049d01ce8
the issue didn't appear.
