Michael, Robin

	Let us know if the reported live load is increasing and diverging from the on disk size.

	If it is can you check nodetool cfstats and find an example of a particular CF where Space
Used Live has diverged from the on disk size. The provide the schema for the CF and any other
info that may be handy. 

Cheers

remember when they were fixed, but that could be your issue.  Are you using compressed column
