It's in the FAQ, naturally:
3.57) How can I have more than 128 X windows clients?
    When you get the following errors, you've run out of X sockets.
        Xlib: connection to :0.0 refused by server
        Xlib: maximum number of clients reached
    By default, the X server has a limit of just 128.  In order to
    increase this limit, you need to run at least Solaris 8 or an
    earlier release with the Xserver patch applies that fixes bug:
        4185418 the X server should support more connections
    Then change the Xservers configuration file and add the "-clients 1024"
    option to the X commandline.

Since I'm running Solaris 8, I can change max clients.
