How about plugging in more memory ?
40MB seems a bit low for a database server footprint - well, certainly depends

But if your machine starts swapping with an extra 40 MB of memory consumption
I'd say the machine is undersized for the application. I usually have around
500 MB free memory with everything running. Memory is cheap nowadays...
