I too am hurting...I've been having a similar problem on terminals that get
powered off and then powered on quite frequently. One terminal refused to
reconnect for three days(!). I've also got the complication(?) that I'm not
running ddns updating on my server and don't use DHCP to send hostnames to my
terminals - I just map any possible auto-assigned IP addresses to a hostname in
/etc/hosts and dhcp just gives them enough info to boot up.

The only real info that I've dug up suggests that I increase the maximum
session count in gdm.conf...hasn't seemed to help me much.

Sometimes by rebooting the terminal a few times the problem clears and the
login screen becomes available again. This is the only tangible problem that
I've encountered while running LTS on RH 8.0 (tho' mozilla occasionally hogs
100% of cpu time.....glad I'm running a dual cpu system :o) )

What was the old thread you started Jeff? (me being lazy and not wanting to
hunt for it)

Any ideas anyone? Anyone else seeing this problem/found a fix?

I feel your pain.  There is an old thread on this topic that I believe I
started.  Usually a station recovers in about five minutes from an unclean
shutdown.  However I have had to resort to changing the stations hostname
in dns and dhcp to recover it without bringing down the server.  Surely we
are not the only one who've experienced this problem.
