Xlib: maximum number of clients reached

[Joe Drew <joe@drew.ca>]

Ever since I upgraded to Xorg, I am getting problems like the following:

Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached

after I leave my machine on over several nights. All that the machine
does is run electricsheep (xscreensaver) and a nightly build.

Once I get to it and it's in this state, the only thing I can do is log
out of gnome and log back in.

Clearly something has gone wrong. How can I figure out what's using up
my X sockets?

Thanks,

Joe
