It is not excessive and I would expect it to work.

As root,run the following command:
	lsof -c X

It will show all files that are open by the X-server, the entries with 
something like "/tmp/.X11-unix/X0" refer to client connections.

You can easily count them with:
	lsof -c X | grep X11-unix | wc

If that number is very high, you may look at the output of ps -aux to see if 
there is a certain program showing up very often.

Cheers,
Waldo
