This system is a 3.0 Ghz P4 with 1 GB ram in an HT configuration.  Every once in a while it appears to run 50% cpu usage permanently.  I am believing that is actually 100% of one virtual cpu.  top shows the offensive process to be gnome-cups-icon.  A while back I found a discussion of this problem with a suggestion that the problem could be solved with "sudo killall -TERM gnome-cups-icon".
