I've installed OES sp2, run rug to update it (successfully) then
attempted to add VNC through YAST, and the server hangs with the YAST
screen showing Checking Dependencies. The NoRM Health Monitor shows the
CPU running at 100%, and processes shows y2base and owcimomd using up
all of the CPU, until it fails because the server is too busy to show
NoRM anymore.

The server seems to be running fine, until I try to run YAST. Assuming
that I can find instructions for installing things without using YAST,
does this indicate that the installation is so seriously flawed that I
need to start over?
