System Data is at the bottom of this report.
I am getting a consistent hang of my iMac (forcing me to reboot) after
running larger screen size apps through the PDE. I am using P3D and pretty
reasonable code but larger arrays of boids (2000) and large
size(1600*2,800,P3D) screens. When the app is running (after some
minutes) it may or may not hang.

My guess is that this is some form of memory leak (smells like it), as i
have also had trouble opening photoshop after running my processing app
lots of times through the PDE.

I'll try to narrow it down and report back. I can't see any unitialised
var's and i understand that Java/Processing does it's own garbage
collection (it's weird not having to deallocate anything.

That's outside our control, either an Apple Java bug or a problem with
their NVIDIA driver code. There's nothing we can do from inside Java that
would cause a kernel panic, because the code doesn't go anywhere near that
low level.

Thanks for checking and i guessed it was something odd. Just wanted to
know for sure. I'll try on one of my other mac's... It's no big deal for
now anyhow.

Yeah, sorry I can't be of more help but thanks for the report anyway.
