Recently my Quad has sleeping issues.

It goes goes to sleep and wakes up from sleep without a hitch. Everything was cool, I was never shutting down my machine, unless required by an install, Since a few weeks, it goes to sleep and after a few hours all the fans start running full blast and I can't do anything else but pressing the power button until my Quad shuts down.

Any idea?

P.S. I'm up to date, I haven't added anything (memory, disk or anything else) since I bought the machine, I regurlarly fix the permission and everything.

Thanks.

Open Console and see if you can find some Panic logs.

Here are a few things you can try.

You may find it helpful to search the apple support discussions forum

http://discussions.apple.com/index.jspa

Are you getting any red lights showing on the front of the box? (see manual)

Check the permissions from the OSX install disk.

reset the pram (how to is in the manual)

The 'sleep' can be a problem on power macs and it can be caused by anything happening that it dosen't like, so its hard to nail down. Reading the logs may give you a clue.

Good luck.

Is the unit also "waking", or are the fans just revving? Is it regularly happening, and if so what time of day, or night? Could it be the regular schedule of the chron scripts???

I saw your post at the seti thread and they tell you the Quad isn't designed for
24 hour per day operation? I beg to differ - a machine touted as professional
should be able to handle this sort of behavior. Unreal.

Absolutely; they suggested that I should use a server for 24/7 operation.

Yeah, any desktop PC or Mac should be able to run 24/7. I've had mine on 24hrs a day for a few days continuously, not 24/7, but there is no reason it couldn't do 24/7.

Sure, a server is better equipped for 24/7 high availabilty critical apps, but you don't really need that for SETI.

It's having a Kernel Panic.
Repair Permissions. Verify the HD.
Have you added any periherals or RAM lately?
Have you run the Apple Hardware Test off the System DVD?
Check the System or Panic logs for a hint on what's causing it.

Like I said on my post:
"I'm up to date, I haven't added anything (memory, disk or anything else) since I bought the machine, I regurlarly fix the permission and everything"

I haven't run the Apple Hardware Test off the System DVD? But I did a 120 hours video editing job and I didn't chrash or had a weird behavior other than a firewire drive dying on me.

The unit is not waking up, the fans are just reving full blast.

First it happend when I was away for the weekend, when I got home there was the sound of a turbine coming from my office, so I don't know if it did this for a a few hours or a few days.... I prefer not to think about it.

The second time, it woke me up in the middle of the night.

The third time it happened in the middle of the day while I was in my office.
Since then, I always shut down my machine. I hate having to boot my computer when I need to use it.

Ill try some some of your suggestions. Thanks

Because I can afford it!

Look in /var/log/system.log (or one of its backups system.log.{0,1,2,...}.gz) for something like

.....

If you see this, the machine has automatically gone to sleep due to a hardware problem, most likely over temperature in one of the CPU cores. It looks like 100C is the maximum temperature.

Also, run the Apple Hardware Test (it's on the original install disk). The machine may run for awhile in normal operation, but if you have a problem the Hardware Test should fail, and some of the diagnostic LED's may turn on. Get it fixed under warrantee. Mine is in for repairs right now.

Interesting , I use folding@home here on quad mac without any problems. Apart from that, this is a seriously haxied system even having codetek virtual desktop pro.

When my air conditioner got broke, I kept putting it to sleep and back dozens of times a day, not a single problem happened.

Apple hardware test is my suggestion too. I better tell how long it takes on a system with 2.5 Gigs of RAM (Quad Mac) 40 mins

Don't run it at 3AM or something btw. All fans and liquid pumps full speed.. Evil!

Also get this http://www.versiontracker.com/dyn/moreinfo/macosx/24043 (hardware monitor)

It does its job fine here.

I better say something about Quad G5: This is a workstation. It will sure handle running 24/7 UNLESS there is a hardware problem. Sometimes weird things happen. My previous G5 1600 power supply fan got locked by persian cat fur

I've been having the same exact problems ever since I bought my Quad in December. When I put it to sleep it sometimes wakes on its own. Sometimes I walk away while rendering dvd's or FCP projects only to come back to a black screen and the fans going full blast and I have to hold the power buttin to turn it off. Sometimes I'll be working on a project and the screen gets that greyed out image with multiple languages telling me to restart (kernel panic?). I am on round 3 of RAM from OWC, strange thing is that it behaved this way before adding RAM and I have re-arranged the DIMMS several times and the machine always reads some type of error on the same slots. I also have issues with the front FW port, I'll have a drive attached and working on a project and then poof it's gone and I get the don't unplug without ejecting message. This has caused problems several times and I needed disk warrior to bail me out. I really am starting to think that I have a few bad RAM slots and a bum FW port. Its strange though that I have been reading others having the same type of issues with this machine.

we're getting sleep issues with one of our quads, in the log it's vvery clear one cpu is over heating and it's going to sleep in a defense mode...

it's had fans on full blast after a certain os update -- can't remember which (or coincidental to that time).
it also had a power supply replaced very early on.

check cpu b0 and cpu b1 diode - near water boiling temp, and the wattage is like 170% of the others.
i think if you let it sleep long enough for it to cool, it will wake. i'm able to wake it sometimes. sometimes user just crashes it completely trying to wake it.
