I am receiving the HTTP 503 error now and this started after a power outage that occurred today. I did uninstall the 4.9 version and re-installed 4.8 but I still am receiving the error. I did also try the 5.0 beta that is out there and had the same issue. I have confirmed that I have all of my ports set properly and the program is running. I pulled the subsonic-service log and I see some errors in there however I am sure what they mean exactly and how to correct. I have done multiple uninstalls and re-installs and I am still getting that error. I see where some people have mentioned to delete or move your db file, but I am not seeing that in my Subsonic C drive folder. I also stopped all of my Java processes and stopped and restarted Subsonic and that didn't work either. I am just wanting to start from scratch at this point and reload everything, but I am not able to get to that point even. I am using Windows 7. Any help on this issue would be much appreciated.
Thanks!
