exactly as it is saying. It respawns xdm/kdm too quickly because there
is already another instance running, and if 10 or more spawn within
something like a two minute period or 30 seconds something like that,
then init will pause attempting to start that process for 5 minutes.
Then try again, thinking that the application is possibly
misconfigured. This gives the system administrator a chance to change
what's (potentially) wrong so that the application/daemon will work
without the system being so loaded that it becomes unresponsive, etc. etc.

harmless. seems that you have an unpatched version of X that is still
attempting to change the ownership of the tty on which it is running.
This will go away in the newest version of LTSP and/or if you were to
run X 4.

Wow! Kernel oops. Don't really know how to help you there. Did you
compile your own kernel for the server? If so, you might want to
upgrade to one of the later versions (2.4.14 or 2.4.16 might do OK). If
not, RedHat has 2.4.9 kernel RPM's available.
