Internal Server Restarts at Random

Hi -

I'm running a test system under XP using CF8. On of the processes I run does timing during car races, and my need to run for several hours.  The problem I'm running into is that the internal CF server will simply restart at random, sometimes after 20 minutes, sometimes after more than an hour.  The logs show nothing, only that the server has started up, not why it shut down.  The process runs as a page request, and I have disabled request timeouts.

Any ideas, or do you need more information?
