Failed to remove RDD error

Fri, 30 May 2014 18:24:07 -0700 

I'm running a some kafka streaming spark contexts (on 0.9.1), and they seem
to be dying after 10 or so minutes with a lot of these errors.  I can't
really tell what's going on here, except that maybe the driver is
unresponsive somehow?  Has anyone seen this before?
