Re: heatbug prob

The colour allocation problems should be handled by Tk - it prints the
warning, makes a substitute, and continues on. It's possible that the
allocation problems caused a coredump: in particular, the XColormap
allocation code isn't as polite about allocating colours as Tk is.

Your X server (running on the machine you're displaying graphics on)
has a limited number of colour cells. Swarm apps (currently) decide
how many colours they need and grab them. Heatbugs uses about 70,
mousetrap uses around 20, etc. If it can't grab them, you get warnings
like you saw.

Your X server has a limited number of colours available - 256 is
typical. You can reduce the problem by not running so many
applications that require lots of colours. Netscape is a particular
culprit here, look into the "-owncmap" and "-ncols" flags to Netscape
to contain it's hogging.

The solution on the Swarm side, btw, is to allow private colourmaps
for specific windows. It's one of those longterm plan things.
