well, I can't say I know for sure, but there is a good chance you may have 
bad RAM. consider running memtest86 on it thru a couple passes.
I had a similar problem lately with kscand and kswapd

and it seems I had two single bit errors in one of my DIMMs

you can get memtest86 from http://www.memtest86.org
