---------------------------------------------------------------------
I'll try write a test program to reproduce the fault.
The basic use case is that we have about 100-200 million rows in the database.
We then simulate usage our application that will cause inserts of columns,
deletes of columns and deletes of rows. The simulated usage is run toward both
nodes in the cluster at about 2000 requests/second. After 5-15 minutes the
fault appears and cassandra must be restarted.
One noteable thing is that the fault only ever happened on one of the nodes
(the second) in the cluster. Suspecting hardware fault we replaced that node
only to have the fault appear on the new node. But never on node 1.

I'm working on a test program to reproduce.
