help interpreting oom-killer output

I'm running a modified 2.6.10 on an x86 uniprocessor system. I keep having processes killed by the oom killer at the same place while running LTP. The system has gigs of memory, so I find this kind of odd.

Could someone help me interpret the oom-killer output? The first log looks like this.


oom-killer: gfp_mask=0xd0
DMA per-cpu:
cpu 0 hot: low 2, high 6, batch 1
cpu 0 cold: low 0, high 2, batch 1
Normal per-cpu:

cpu 0 cold: low 0, high 32, batch 16
