Everytime I start rhythm box the process rhythmbox-metadata starts up and uses 100% cpu on one core, causing the computer to heat up and the fans to start rotating hard. I have an external drive with about 450GB of music. rhythmbox-metadata will remain active at 100% cpu for an hour and then stop consuming cpu. This happens everytime I open rhythm box even if nothing changed in the music folder.
How can I stop this behaviour ?
