Okay, that's about 12MB worth of swap, which sounds about right. After running the swapon command, run "free". (Hopefully it's installed.) It should show you that 12MB of swap space.

What I'm getting at is that running out of memory sounds like a swap-less condition, but you've turned on the swap, so that shouldn't be a problem. But it is, so we need to find out what's wrong with it.
