RH9 -> FC1 XDMCP problem in gdm

[Warren Togami]

Jan 27 11:07:45 ltsp-server gdm[2995]: Maximum number of open XDMCP 
sessions reached

After upgrading K12LTSP from RH9 to FC1, this is happening every once in 
a while.  When this happens, thin clients are no longer able to get 
desktop sessions.  init 3 && init 5 will recover from this, but it kills 
all stations that are active.

ps -ef |grep gdm-binary or gnome-session does not show an abnormally 
large number of processes.

Are there any known gdm bug introduced in FC1 related to this?
