It sounds like the application isn't paying attention to the color
model of the X server on the Sun box.

Suggestions on how I debug this?

My web site has a copy of my tutorial on debugging X protocol error messages.

Look at what xdpyinfo (the command line program) tells you on both
displays. My guess is that the application makes an assumption about
the display depth or the default visual or something similar but that
assumption doesn't hold for the Sun display.

For example, if the DEC display is 8 bit with the default visual being
pseudocolor and the Sun display is 24bit true color the app has to be
smart enough to recognize the difference if it is allocating colors.

If you have the code look at where it call XCreateColormap(). If you
don't contact the developers. If you can't do both I can only suffest
that you configure the Sun display to match that of the DEC, if possible.

Some general tips.

[1] extern int _Xdebug;

int main(int argc, char **argv)
{
_Xdebug = 1;
...
}

You can then run a debugger and find the line that's failing.
X otherwise tends to batch things, to improve performance.

[2] Somewhere, you're trying to create a color map; the
create is failing. (Most likely, it's because you're in
a TrueColor visual; TrueColor doesn't like colormaps,
except perhaps the single system one. However, absent more
informaton that's just a wild guess.)
