This post is coming from a quad 2.5 G5 and TenFourFox has never
exhibited any such behaviour, nor on the dual 2.5 that a friend is
TenFourFox stresses the hardware and memory more than many other
apps. Your problem suggests either RAM or the logic board. If the
front LEDs show a red light when the kernel panics, you may have an
impending hardware failure. If you have Apple Hardware Test or
Applejack available, consider checking your RAM as well, since that
is easier to correct.
On some marginal G5s, downgrading to 10.4 from 10.5 has bought
users some time, but these machines will eventually fail also.
Thanks for your quick reply. It is possible that RAM is the
problem, because it was upgraded several months ago. But wouldnt I
get kernal panics while running other apps too, if it was the RAM?
I am also a little confused what you mean by "red light." The only
light on my G5 box is the, white restart light on the front. It has
always remained white. Also how does downgrading the operating
system, fix this problem if it is a hardware issue? I do understand
though, that my G5 is a little outdated considering its only a
single core. I guess I will try the apple hardware test, but I hear
it doesn't work very well. Once again thanks very much!
The G5 should have status LEDs at the front of the unit (inside
the case, visible through the vent holes). They are different from
the usual white power LED. If the red light comes on when it
panics, that is usually a bad sign. If the red light is on all the
time (which fortunately does not seem to be the case here), that is
almost always a bad sign. They are normally off. The later G5s have
even more, but all G5s have the red LED.
Downgrading the OS doesn't do anything to fix the hardware; it
merely takes the load off the unit and requires less memory.
I finally got another kernal panic today, actually I got two. I
searched all over for these status LED's and even took off the
cover, but didnt find anything, so I assume they arnt turning on.
Also a couple of moths ago I ran the apple hardware test overnight
on a endless loop, it didnt find anything. The strange thing was
the kernal panic I got today, I wasn't even using Tenfourfox. It
was just open in the background without any web pages loaded. What
does my g5 have against Tenfourfox? I dont know how to find the bad
Ram (of thats the problem). I normally only get a kernel panic no
more then once a week (even though I got two today). So it will
take ages to test individual chips of Ram.Thanks a lot for your
If you get kernel panics as much as once a week, I'd say from my
~10 years experience that this is highly unusual with Mac OS X.
Your computer probably has nothing against TenFourFox, you have a
hardware failure (RAM or logicboard, as suggested), or a
misbehaving kernel extension (Logitech mouse driver comes to mind)
or a failing external USB device (which is again a hardware
problem) that's causing your problems. With a clean Mac OS X and
healthy hardware, anything above 1-2 kernel panics a year is
something I'd worry about.
Thanks for the quick reply. I understand that, but I just find
it strange that I only get kernel panics while TenFourFox is open.
Not once have I gotten a kernel panic when it wasn't. I understand
TFF is quite taxing on the hardware, but I have ran plenty of hard
tasks through this G5 such as encoding HD movies, and not once have
I gotten a kernel panic. Thanks, I will look into testing the
I think your a little confused. It was still running when I got
the kernel panic, just in the background with a few windows open. I
just was checking my email I think from the built in Mac email
program. That was a long time ago. I eventually stopped getting
Don't ask me how but shortly after I last posted it just went
away, I didn't have to replace RAM or anything. I did go into my
system library and delete anything that had to do with
firefox/tenfourfox in case it was interfering, so T4FF could create
new ones. I'm not sure if that was the fix, but I stopped getting
KP's around that time. But how you describe it sounds like your RAM
is bad, I'd remove it and see if the problem goes away.
I have a Mac Mini G4 running OS 10.4.11, and the same problem.
When I start TenFour Fox, I almost every time get the dark screen
with the "you have to restart" button. After restart, T4F works
My Mini is in original condition since 2005, I never opened it or
I am starting to suspect T4F as well...
I will leave it off the next few days and see if things panic.
plus, I run internet radio through iTunes all afternoon while I
and I've begun to suspect that IT might have something to do with
maybe it doesn't play well with T4F... or who knows.
I may have mis-perceived the relationship.
I tried a RAM test using applejack, and something went wrong.... it
appears to have locked up or gone south during the RAM test.
I will try again and post.
Although I appreciate the concerns, it's going to be next to
impossible to distinguish this from hardware failure without a
reliable means of reproduction. I haven't ever had a kernel panic
from TenFourFox on the 4 test machines, though I can certainly
panic them with weird USB devices, bad RAM (the fileserver had a
bad stick), and other hardware or driver issues.
