I am pretty sure that the VD0: memory errors are due to running out
of FAST ram before the disk is full. If your board auto-configures,
then the non-display system memory, and any programs that you run,
start using up your fast ram. How full is your VD0:? and how much
free fast ram do you have just before you run your program, and after?
Is there any correlation between how much you put in vd0: vs how frequently
/when it crashes?

Also, wild pointers (running off the end of arrays, etc) have an attraction
to trashing vd0:'s integrety.  (I wish Amy had hardware memory protection...)
You might make your vd0: smaller (say 1.5 Meg), so that it can't run out of
fast ram. I seem to remember the docs saying something to the effect
that it is better to fill up vd0: than to run out of fast ram, as then
it may crash...

hope this helps...
