This looks odd. I'd have said it was a sign of a memory leak in the
driver if it wasn't for the fact that you are sure things are OK if
the working set remains constant. Does this apply even if you keep
working for many hours? Is it really the working set or simply the
uptime which triggers the problem?

Cheers,
Stephen.
