I just want to confirm that I have this same 100% CPU issue. I can’t really pinpoint when it happens; obviously I get high CPU usage when other people connect and it starts transcoding FLAC stuff, but even when no one is connected and listening to music, it still bumps up to max CPU usage (on both cores). Since it’s hard to pinpoint when it happens, and I’m not always paying attention to my server, I’ll often come back hours later and it will be at 100% and I won’t be sure why.
