As far as paging goes, the UnixPC definitely can page correctly.
I was running a 512K system for a while (yes, it was very painful)
and EVERYTHING would page out.

I really think the problem you are experiencing is related to
a system fault, not insufficient memory size.  I run for months
with 2.5 meg with no problems, but have nowhere near the amount
of drivers and load it sounds like you have.  Sounds like either
a driver bug or a real kernel bug.

At this point, a planned restart might be a reasonable option
rather than pursuing something that takes so long to reproduce.
Weekly or monthly would probably be fine.  I've seen others that
believe this is a good idea.
