Big /proc problem

[ahr1@comcast.net]

Somehow I've done some not-so-wonderous things to my RH9 installation:
I have a Monsterous (348Mb) /proc/kcore file which I cannot remove or edit 
down.  It is preventing me from using the system as it has filled the / 
partition to full.  I can't change permissions (even as root), rm it, or vi it.
Two questions - what can I do to get rid of it? and, - any idea what is the 
underlying cause of this file's creation and expansion?  Any help will be 
appreciated.
