I am having this pegged CPU utilization issue as well.
I am running:

Running on Windoze XP Pro with SP2, AMD 1.4 GHZ, and 1.2GB RAM.
I have scanning disabled and no one is accessing the server as this is on my home private network.
I start the server up with no clients hitting it, come back in a few hours and the server is at 100%. Memory utilization is only at about 8,000k on firefly.exe and 5,168k on FireflyShell.exe
Update: My server was running for 23 hours at 1-2% CPU utilization. On the 23rd hour, firefly.exe flatlined at 95% utilization. I have logging set to the highest level and no new events are recorded from the log events seen above.
About two hours ago a connected two clients to the server, an itunes client and a Banshee client. Both clients connected to the server, loaded up the playlist and then I closed down the clients.
