i too have been getting frequent kernel panics. at first i thought it was
just clunky code. but when i use two different machines (work and home) and
my home computer is the only getting the kernel panics.

however, unlike some of the posts here mine happens when running the code.
not when editing. usually a few seconds after hitting "run"

i'm using Processing 0127 on both machines.

ok that's a lot of info. if you need anything else from me let me know.
hope this can be resolved.

thanks.
Ken

whoa, at a minimum, *do not* use processing 0127. please use the up to date
version.

wow. i feel dumb... hadn't recieved an update notice, i must have
unknowingly disabled them. i have downloaded Processing 0135, and for a
while i thought everything was fine.

however, i just had a kernel panic, while trying to run a script.

I'm getting kernel panics irregularly, but multiple times a day, in 0135 on OSX 10.4.10, always
as soon as the sketch runs. it's not every time - often a sketch will run 20, 30, times in a row
before kernel panick. same sketches are stable all day in 0124. the first consistent thing i can
see is that they all use libraries of some kind - some use minim, others use oscp5, others use
OpenCV. i don't think i've been able to get a panic without any libraries loaded. not sure what
else helpful i can offer at the moment other than, ken, you're not alone :)

i've been getting them rather frequently. if it would help i can post a
link to some of the scripts i've been using. as it's increasingly
frustrating, that i can't seem to replicate it.

using 0135 beta.
osx 10.5.2 intel macbook

Ken

i'd love to help, but i can't do anything unless you can replicate it.
unfortunately, the vast majority of users are not dealing with the same
issues so i'm not able to help you at this point. keep an eye out for
libraries that might be out of whack, or other java programs that might be
causing problems, or errant files in your Java "Extensions" directory.

and again, the bottom line is that technically, there is *nothing we can
do* inside Processing that would cause a kernel panic. there is no native
code in the macosx version, so we're at the mercy of what might be crashing
on the apple side of things.

at first i thought it was libraries as well, but i've been running some
simple processing sketches that do not use libraries. and although it's not
frequent enough to tell, i think it might have something to do with using
type. i'm not using createFont but i am doing this:

PFont[] typeface;
typeface = new PFont[2];

typeface[0] = loadFont("LucidaGrande-9.vlw");
typeface[1] = loadFont("Gotham-Light-33.vlw");

most of the time this is how i deal with typefaces is this a big no-no? (i
hope not cause it makes my life easier)

i'm not 100% sure how to error check it. any tips would be helpful, i'm not
sure what my java "extensions" directory is. and i don't really use any
other java programs.

thnak you for your help.

it appears i may have found the problem.

after having 3 kernel panics in a row within about 5min of each other. i
noticed this line in the error report:

Kernel loadable modules in backtrace (with dependencies):
at.obdev.nke.LittleSnitch(2.0.28)@0x7c3000->0x7ecfff

so i uninstalled the app little snitch. and violá. i haven't had any kernel
panics since then. everything is running smooth. then i found this on the
site for little snitch

"Important note for Leopard users upgrading from Little Snitch 2.0 or 2.0.1

Little Snitch 2.0.2 fixes a potential kernel panic during shutdown on Mac
OS X 10.5 Leopard."

http://www.obdev.at/products/littlesnitch/download.html

so my apolgies for posting a processing bug, when it was obviously another
apps bug. but the odd thing is only processing seemed to cause the kernel
panics.

i'm 99.9% certain this has solved my problems but if not i will post here.

thanks.
Ken

k, i'm closing this bug in that case.

*** if anyone has other kernel panics when using processing, please file a
new bug. do not reply to this bug as it has been closed. ***
