I experienced this today on a pretty fresh install of 12.10 64-bit. It became problematic when I ran VirtualBox (with lots of memory requirements).
I Manually killed all Rhythmbox processes. I was listening to the "Radio" stations. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to rhythmbox in Ubuntu. https://bugs.launchpad.net/bugs/1080041 Title: rhythmbox-metadata process constantly fills ALL of the memory, then drops to 1% until killed Status in The Rhythmbox Music Management Application: New Status in “rhythmbox” package in Ubuntu: Confirmed Bug description: When first started, rhythmbox's rhythmbox-metadata process tends to grab all available memory (up to 1.1 GB) for a few seconds, then releases everything for a while. Then it slowly creeps up to 1.1 GB again. This repeats indefinitely until I manually kill the offending process, at which point it respawns, although no longer taking up more than 10 MB.
