There are some bugs in the VM subsystem that cause this. When long lived
processes start paging, you end up losing portions of your swap
space. This is harmless except if you run out. People with lots of
memory don't notice the problem. Hopefully, someone will volunteer to
finally rewrite the VM subsystem and the problem will be fixed.

I would suggest that you simply have the machine reboot itself on a
weekly basis or some such.
