I have had a similar problem and found that the only solution was to put a
sleep between each x client initialization from .xinitrc.  Here is a sample
of my .xinitrc that starts up zillions of things (I have a 19" 1600x1200 
monitor, so I can start lots of things and still have room)

Good luck.

Sample .xinitrc file:

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/usr/lib/X11/xinit/.Xresources
sysmodmap=/usr/lib/X11/xinit/.Xmodmap

HOST="`uname -n`"

#
# The following two variables are used to pause the software initializations
# between each step.  When too many things are started at the same time, the
# server gets screwed up and gets into a state where all new connection 
# requests just hang (i.e. they are not refused, but they never succeed nor
# timeout).
#
# Set both to nothing (comment them out) if your server does not have this
# problem
#
SLEEPCMD=sleep
SLEEPTIME=7
