subsonic stops

I have encountered the same problem after some adding and deleting files in my NAS two weeks ago. I have done many things trying to make it work again, turning it on and off for many times, reinstall it using either the 2.0 or 4.7 versions. They all did not work and it still crashed. Finally, I re-installed the subsonic 2.0, then updated it to 4.7 beta version. I could launch the page even the green light is not on. I disabled the automatic media re-scanning and I disabled the Podcast re-scanning button. I re-installed the ReadyNAS firmware by pressing the reset button with a clip and power on button for 5 seconds. The problem solved and subsonic won't crash anymore for the past 2 days. I hope that can solve the problem.
