VirtualGL only opens one connection to :0 (or the specified 3D X server) the first time XOpenDisplay() is called, and it reuses that same connection for all subsequent 3D operations. Thus, VirtualGL is only 1 "client" from the 3D X server's point of view. I think Xorg can have a max. of 256.
Minimally, this appears to be due to an ill-behaved application, although it might be possible to work around it if I knew more about the underlying cause. Googling maximum number of clients reached x11 reveals this page http://www.linuxquestions.org/questions/slackware-14/x11-maximum-number-of-clients-reached-864156/ which has some potentially useful command lines that you might be able to use to further diagnose where all of the X11 connections are coming from.
