Lee,
This still sounds very much like problems we were seeing. As best I
could track it there is some issue with dynamic allocation of memory
(sometimes it would work sometimes it wouldn't). Try running your app
with a big chunk of memory allocated up front. Something like:
java -mx40000000 -ms40000000 yourProgram
It's a very annoying problem because sometimes it'll run flawlessly for
hours, sometimes it'll die before bringing up the Canvas3D, sometimes
it'll die just about dang near anytime. But since allocating memory up
front it hasn't died at all.
