@bander, The strange thing is the crashing issue has only occurred TWICE in the last 6 months. Is it possible the stored album being played or the streaming album caused the server to stop working?
What stored album was being played or steamed when the server crashed (stopped working)? Could this be a software issue? This might help identify the issue.
The Internet connection questions asked by @gdnrbob above also need to be answered. Please keep us posted
