[SOLVED] High CPU usage on Mac

I'm using Serviio 1.0.1 on a Mac.
I think I'm having a problem with the library indexing. Normally Serviio uses a lot of CPU when I first start it up, then it drops back to zero after a few minutes. But now for some reason it's using 100% CPU constantly after several days of running. Serviio Console shows the green light "Checking for new files".
Other than the CPU usage, everything else appears to be working fine. If I add new media files, Serviio finds them within a few minutes, and all the videos play fine.
The CPU usage has never spiked for this long. Even when I add a new media folder with thousands of files it usually only takes a few hours.
Oh, here's another clue. If I run Serviio Console and select "Exit Serviio" from the menu bar the app freezes and I have to force quit. Usually when I do this Serviio and Serviio Console quit gracefully. When I restart Serviio (even after a reboot) the CPU usage again spikes to 100% and stays there for days.
It seems like it's stuck in a loop. Any idea what's going on?
