Cody Stevens is still having a problem:
If I stop carbon-cache util drops to nothing.

 iostat -d /dev/sdb1 -x 60 2
Linux 2.6.18-238.19.1.el5.centos.plus (graphch02.int.com) 	09/15/2011 	_x86_64_

The box has 24 G of memory.  Troubleshooting this I have seen carbon-
cache.py using 17G or more depending on what I had my settings at.
