[ale] What is krefilld?

[msmith at risklabs.com (Matt Smith)]

I'm seeing a lot of processor time spent on the krefilld process, but am
having a very hard time determining what it does.  I haven't been able
to find much information about it.  Here's what I'm looking for.

--What it does

--What would cause it to run a lot

--Kernel parameters/etc that can be used to adjust how/what/when it does
whatever it does :)

Of course, ANY info is appreciated!
