You show 128M Phyical and 128M Swap.

In a unix system the memory of the system is counted as a single unit,
with a differentiation between physical and swap a secondary measure.

When you see the message, the system is including physical memory,
or the RAM in your system, with the Virtual memory.
Other "names for virtual memory are Swap and Paging File.

When the OS requires more memory to do a series of tasks than the
system has, it will write some of the memory on the hard drive,
finish a task and reread the meory, or swap it in or out.

When a task is completed, the use of swap drops.
If you are seeing this message with any frequency, look at the top and
monitor
the processes closely to note what activities are sucking up the most
memory.
It could be a runaway process like ZoPE or just a lot of POP3 mail requests,
or even a mailbombing.
