Using version 0.6.4 I think theres a bug when another app is running while testing, such as WMP or browsing the net. When watching a movie while testing it tends to fail within 1 hour regardless of settings, when just running LinX alone it went for over 170 runs all memory (4850 MB) compared to less than 20 runs when watching a movie or browsing the net with the exact same settings, temps, and memory use.
