12AM... Computer uptime: 11 days, 5 hours.

Computer freezes.

Most recent: 6 days, kernel panic
5.5 days, kernel panic
6 days, kernel panic
7 days, kernel panic
12 days, kernel panic

WTF is up with my g4? This has been going on now since I've owned it...

And this is the last time I put up with it.. today when apple opens well to put it short, I feel sorry for the guy that answers my phone call.

The most annoying thing is with time the uptime 'average' has gotten longer but it's always the same reason. It used to be this machine could go maybe 3 days and now it can usually go about 5.. sometimes 10-12.

But never more. I dunno why or how but ever since I got this computer. With 10.1, in fact, it would do it every 3. In 10.2 it takes longer but it still happens for the exact same reason.

No log info.. from what I've seen. Sometimes kernel panics (actually about half the time) are fed in text. OS 9 has told me befoer there might be CPU errors but it's only happened twice. (then again I've only used OS 9 so many times).

The many times I've called apple they point fingers everywhere. Their excuses have been anything from that maybe I'm running bad programs to the way my computer is stored (on my table), to the way I use my computer (like anyone else would) to some totally rediculous things.

They even once said they couldn't guarantee that I was treating it properly.

The most recent was when compusa replaced the ram under apple's instruction. Apple said that because there was non-apple ram in there my computer wasn't covered by them anymore.

My guess? CPU probably. Ram maybe? I do recall having frequent kernel panics even before the ram was replaced but the CPU never has been.... I ask apple.. they deny it, they lie, they get angry, they hang up on me.

It's now been over 2 years since I first complained about it.

-.- will call today. Probably get the run around, have to take my g4 into a store, end up being without my main server/router/work machine for a whooping 2 weeks while apple tells me to try and buy another one of their computers (now why would I do that?), and etc.

Of course I'm set on asking them to replace the CPUs. This machine has had enough troubleshooting and testing to make a technician blush.. perhaps they can get it done onsite or at least have a store have everything ready so I can wait an hour or two and have it all fixed. :sigh:

But anyway... all in using an apple computer as a digital hub (routing and serving are requirements of mine), at the same time I get criticised for it and see fewer reasons...

It really gets disgusting when you have the thought hanging in your head "when is my computer going to kernel panic" and having to save things that frequently. I bought an apple machine with the knowledge that they were supposed to be stable and so far I've been proven the total opposite.

And I'm jealous. My bro has his nice little imac, never been a problem, always working, etc. Thank goodness, I suppose.. but geez why can't my tower be like that?

Kernel panics are almost always caused by hardware issues. Exception: mount an FTP volume in the Finder, and try to upload.

Clean and oil your fans. Don't forget fans on PCI cards or especially the graphics card. If need be, pull the heat sink off the CPU(s) and apply fresh thermal paste. Your uptime seems to be increasing as the seasonal weather gets cooler - we are approaching the end of summer.

One of the hard drives could be on the edge, but that is unlikely because the problem has been going on so long. Dying hard drives do not get better or hang on, they get worse.

Some USB peripherals do not agree with OSX all the time. Apple has been working on it, later OSX releases cause fewer USB devices to generate kernel panics, or generate them less often. Do you have any 3rd party USB devices plugged in?

You are using this machine for many things, perhaps you've added PCI cards and hard drives. When the case is closed, do any new ribbon cables obstruct the internal air flow? Apple went to great length to route and tie off the cables so they obstruct nothing when the case is open or closed.

sorry to hear about your problems with the G4, but what can we do?

Could be the CPUs are running too hot. Doubt it. Machine's under warranty so I will NOT touch the heatsink and the geforce 4mx in there doesn't require a fan. no additional HDs or things and the ribbons are still, for the most part, as they were when I bought the machine

The HD was replaced, motherboard was replaced, ram was replaced, GPU was replaced.. problems persist.

Usually no. isub at times but I've tested that thoroughly and at least in 10.2 it hasn't caused any probs at all (I just got off an 11 day uptime with it plugged in and have had 11 day uptimes without it plugged in.. no change in behavior. Only other thing I usually have plugged in is the printer, which I changed during the problematic stages. Nothing changed... yet again have run machine without printer.

A usb 2 card. But that was added about 2 months ago and these problems have been around for far longer.

I can't point fingers at anything really.. the cooling? doubt it.. the 3 day uptime thing was almost a year ago.. and I've had no stability interuptions as summer came and went.

Machine's also sitting in a large cleared area on the table. there's at least 6" of space in every direction (except underneath where there's standard ground clearance allowed by the case).
