Seems if some of those who wish to run systems 24/7 are the ones experiencing this problem.
XP Pro SP3 Avast! 7.0.1451 2GB RAM no problems seen so far, but then again only run system when actually using it.
Great thread! Great diagnostics. Should be a standard part of the beta testing process, it is likely those who have lesser memory (256-512 MB) might display this issue sooner, rather than later.
@ Herrminator,
Is problem now resolved? It was an update that fixed it?
