Oracle 8.0.5 on Linux SMP kernel panic

I'm trying to run Oracle EE 8.0.5 on Linux Redhat 6.0 with Kernel 2.2.5-15 SMP. (custom kernel). I have 512MB of memory on the machine.

When I perform a large query it panics (large table join). I've enclosed a Blurb from top below. The kernel panics with a swapper error. The swap space looks good.

Is anyone using Oracle 8 with Linux SMP? If so, have you experienced these problems?
