I have what may or may not be the same problem. I'm running 5.1 on a
Windows XP box that also runs iTunes. I've got the "use iTunes" button
checked in the server. Much more often than I'd like I get a "lost
connection to server" message on my Squeezebox when I go to play a saved
playlist. Checking on the server during these times shows that the slim
server is banging heavily on the CPU. This lasts for an amount of time
that seems proportional to the size of the playlist, that is a shuffle
of all tunes (about 4K songs) will peg the CPU for a couple of minutes.
A shuffled play of a 24-song playlist pegs the CPU for about 45 seconds,
which is still long enough for the Squeezebox to complain about a dead
server.

I tried disabling the look for artwork option. This seems to have
helped, but now I get no artwork in the web interface. Seems like a
step back to me.

Its not meant to be a solution, just confirmation. I dont want to just assume
it sthe artwork routine and tell you there is a fix only to have you find out
later that it isn't :). This fix should speed things up by a factor of 8, plus
adds scheduling so that the routine doesn't hog all of the slimserver resources.
